As a defence against predators, the caterpillar expands the third thoracic segment which bears "eye-spots". Hind wing: base and an edging that decreases in width along the dorsal margin irrorated with yellow scales; followed by a broad medial yellow irregular band, a sinuous postdiscal series of outwardly emarginate yellow spots and a terminal series of smaller similarly coloured spots as on the fore wing. Males are slightly smaller. Many of the hairs on the legs and body are equipped with sensory nerve endings which make them sensitive to touch and vibration. Females can have a wingspan of up to 13 cm. Chattopadhyay, Jagannath. The Lime Swallowtail Butterfly (LSB), Papilio demoleus, while beautiful is known to destroy citrus plants in Jamaica. In the tropics this division becomes difficult using the simple characteristics which apply to these insects in cool, temperate regions of the world. In moths this sense is very acute but in butterflies it is often reduced, probably because their day-flying habits enable visual navigation. It is found in savannahs, fallow lands, gardens, evergreen and semi-evergreen forests, and shows a preference for streams and riverbeds. Besides this, the butterfly has a large number of irregular spots on the wing. Citrus Swallowtail Butterfly is a Papilio type of butterfly that belongs to the Papilionidae family. The life cycle and interesting life traits of the Citrus Swallowtail butterfly (Papilio demodocus demodocus). Butterflies tend to fold their wings vertically above the body at rest, while moths hold their wings flat or in a roof-like manner over the body. The Citrus butterfly is a common and widespread swallowtail butterfly.It gets its common name from its host plants, which are usually citrus species such as the cultivated lime. Title: Citrus Swallowtail Butterfly Papilio Demodocu, Author: KelleyHurt, Name: Citrus Swallowtail Butterfly Papilio Demodocu, Length: 3 pages, Page: 1, … Citrus swallowtail butterflies are common in Africa south of the Sahara. At first pale and soft, the pupal cuticle hardens and may be pigmented brown or green to match the background. In many specimens between the discal and postdiscal series the black ground-colour is irrorated with yellowish scales. [12] The typical time for one generation of P. demoleus to mature in the field ranges from 26 to 59 days. Mating takes place with the male holding the tip of the female's abdomen with his abdominal claspers, sperms passing into the female in a special sperm-package or spermatophore, so fertilizing the eggs internally. Swallowtail refers to the posterior extensions on the hind wings of some species. The butterfly can be found in:[9][10]. The caterpillar is a serious pest of many species of citrus. The upper hindwing has a red tornal spot with blue edging around it. [16], Research into the biogeography, phylogeny, and analysis of vicariance relationships dating back to the Cretaceous, of the "lime butterfly" or "demoleus" group, suggest that the group of lime swallowtails diversified in Madagascar in the middle Miocene. The last tarsal segments may bear taste organs. In India, these braconid wasp parasitoids are known to parasitize P. demoleus larvae:[11], In Thailand, a number of organisms have been recorded attacking immature stages of P. demoleus:[11], In Jamaica, an encyrtid egg parasitoid and a chalcidoid parasitoid have been reported. Papilio demoleus is a common and widespread swallowtail butterfly. The head is equipped with biting mandibles which move transversely. The proboscis consists of two long, hollow processes grooved along their inner surfaces, so that when they are placed together they form a sucking tube. However, larvae can be … The larval or caterpillar stage can be considered a pest due to its habit of feeding on the foliage of most Citrusspecies. [16], Six subspecies are recognised in P. demoleus:[11][16], This butterfly is an avid mud-puddler and visitor of flowers. Zoologists usually separate moths and butterflies using complex differences in the wing venation and sexual organs rather than the characteristics discussed above. The Citrus Swallowtail is a common and well-known butterfly that can be found all over South Africa in suitable habitat (it avoids very dry areas). Rhythmic contractions of the body and a lubricating moulting fluid allow the split cuticle to pass towards the tail where it is discarded, the pupa attaching itself by the modified last pair of prolegs, the cremaster. The account of structure and life history given above is generally applicable to most butterflies and moths. © Copyright 2004 - 2020 D G Mackean & Ian Mackean. The scale colour may be produced by a bending of light rays through the scales so that they act like tiny prisms, or by the inclusion in the scales of pigment derived from nitrogenous waste materials. After a few days the larva can be seen through the shell, subsequently escaping from it by biting a hole. Papilio demoleusis native to the Old World where six subspecies are re… The butterfly is a pest and invasive species, found from Asia to Australia. From the fifth instar onwards, the caterpillars now turn cylindrical in shape, tapered towards the rear, and uniformly pale green in colour with a white subspiracular band. [2] These common names refer to their host plants, which are usually citrus species such as the cultivated lime. The second, third, and fourth instars are dark, with a glossy, dark-brown head, and white markings on the eighth and ninth segments of the caterpillar, which resemble a white patch of uric acid deposited in a bird's droppings, helping them escape predation while remaining in moderately open places. The fore wing has the base below cell and basal half of latter so irrorated with yellow scales as to form more or less complete transverse dotted lines, two outwardly oblique yellow spots in cell and a curved spot at its upper apex; a spot at base and another beyond it in interspace 8; a discal transverse series of cream-yellow spots irregular in arrangement and size extends from interspace la to 8; the series interrupted in interspace 5 and the spot in interspace 7 double; this is followed by a sinuous postdiscal series of spots and an admarginal terminal series of smaller spots. It gets its common names from its host plants, which are usually citrus species such as the cultivated lime. Many butterflies drop their eggs among herbage and do not seek a food plant on which to stick their eggs. After hatching from their egg, the caterpillar feeds on a few leaves on citrus trees before pupation. [11], Hand-picking of caterpillars and spraying with endosulfan 35 EC (2 ml/10 litres of water) were the recommended means of pest control by Indian government agencies and agricultural colleges,[23] however, endosulfan has since been banned by the Supreme Court of India. At the same time, a forked, tongue-like osmaterium, normally withdrawn into the first thoracic segment, is extruded and vibrated. Biology of insects, Citrus Swallowtail butterfly, Papilio demodocus, structure, eggs, larvae, pupation, teaching notes and drawings The body of the imago consists of a distinct head, thorax and abdomen, with three pairs of walking legs and two pairs of wings attached to the thorax. The Dainty or Dingy Swallowtail – Papilio anactus – is the most common and numerous swallowtail in this area. Further dispersal events of Papilio demoleus within Seychelles to other granitic islands of the archipelago, e.g. It is most abundant during the rains when its larvae (caterpillars) may cause damage to citrus trees. Adults have grey-black wings with white markings. We would love to get a photo of the adult butterfly if you are able to send one. The eggs of the giant swallowtail are pretty easy to find compared to other butterfly species that resort to trickery and camouflage to keep their eggs safe. [19], The newly hatched caterpillar stays in the middle of the upperside of the leaf. [11][14], As the instars progress, this resemblance is lost. The caterpillars can become so numerous they can totally strip a small citrus of all it’s leaves. Behind these is a spinneret, a press device through which secretion is ejected from a pair of modified salivary glands within the larva. The splitting of the old cuticle is called ecdysis. MOZAMBIQUE - CIRCA 1953: A stamp printed in Mozambique, shows a african butterfly papilio demodocus, also known as the citrus swallowtail, from the series "butterflies and moths", circa 1953. Your Butterfly Citrus Swallowtail stock images are ready. The first instar of the caterpillar is black, with a black head and two rows of subdorsal fleshy spines. [13], The widespread range of P. demoleus indicates the butterfly's tolerance and adaptation to diverse habitats. [12] In the ideal conditions of a laboratory, a generation has been recorded to take place in just over 30 days. A few orangedogs, as the larvae are commonly called, can quickly defoliate small or young plants. - citrus swallowtail butterfly stock pictures, royalty-free photos & images There are five segments in the foot or tarsus. [14] It is also a frequent visitor of flowers in gardens, where it shows a preference for flowers of smaller herbs rather than larger plants such as the ubiquitous Lantana with its plentiful blooms. The remaining ten segments constitute the abdomen, segments 3, 4, 5, 6 and 10 bearing pairs of larval legs or prolegs which are absent in the adult. It can be found at altitudes between sea level and at least 1200m. The other morphologically related butterflies are:[16], The citrus swallowtail (P. demodocus Esper) is found in sub-Saharan Africa, while the other three species are endemic to Madagascar. [5]:52 Above, the background colour is black. [14] Lifecycle The group of insects which includes the citrus swallowtail is often popularly divided into moths and butterflies. The Citrus Swallowtail Butterfly are native to Africa, and they are also scientifically called as Papilio demodocus. [11][14][20], The adults fly in every month, but are particularly abundant during and after the monsoons. Image of macro, insect, black - 113289398 [24][25], "Common lime" redirects here. Desh Prakashan, Kolkata, West Bengal, India. It basks with its wings held wide open on tufts of grass and herbs, and generally keeps within a metre of the ground, even on cloudy days. This page was last edited on 5 February 2021, at 00:24. "[7], "The underside has the ground-colour similar, the cream-coloured markings paler and conspicuously larger. This insect lays an egg in the body of a young swallowtail caterpillar and the wasp larva is nourished from the body juices of its host. Initially, the vital organs are avoided, but by the time the caterpillar is ready to pupate, even the vital organs are consumed. In addition, eggs and larvae were heavily preyed upon by two unidentified species of spiders which were abundant on citrus trees.[21]. At this stage, the caterpillars are forced to inhabit secluded places. The butterfly is tailless and has a wingspan 80–100 mm. As the day progresses, it flies fast, straight, and low. In China, species of fungi in the genus Ophiocordyceps are known to parasitize many kinds of caterpillars, including P. [6] The butterfly is also a very successful invader, its spread appearing to be due to its strong flight, increase in urbanisation and agricultural land use that opens up new areas for dispersal, and greater availability of food plants. In mature trees, caterpillars may prefer young leaves and leaf flush. [11][15], Five related butterflies form the group of lime butterflies in the genus Papilio of which P. demoleus Linnaeus, 1758 is the flagship species, which gives the name to the group. In structure, they are quite unlike the hairs of mammals, being outgrowths of the cuticle and having no root. [12] The caterpillars can completely defoliate young citrus trees (below 2 feet) and devastate citrus nurseries. The early larvae are black and white in colour and do not attempt to hide, while the mature larva with its different colouring withdraws to parts of the plant where its light under parts cancel its natural shadow and allow it to blend with the leaves. Citrus swallowtail (Papilio demodocus) is a brown and yellow butterfly … Larvae develop into pupae, which later develop into the adult butterfly.The butterfly is tailless and has a wingspan of 80–100 mm. [11] Typically, the butterfly undergoes five instars as a caterpillar. If they contact sugar or fruit juice, the proboscis is uncoiled. After this they flatten and become chemically hardened. Occasionally larvae of Papilio butterflies may be seen dried and dead, their shrunken bodies attached firmly to a leaf. The green morph, which is found amongst green vegetation and smoother textures, is light green and unmarked or with yellow dorsal markings. It relies on its quick flight for escape. On the bottoms of the hindwings are two eyespots, as well as two more that are higher up that are usually only visible when the butterfly's wings are closed. [11], Captive breeding of P. demoleus in Riyadh has revealed these data about the lifespan of various stages at that locality:[21], Early-instar "birds-dropping" caterpillar, Despite their two-stage camouflage scheme, some caterpillars of P. demoleus are found by parasitic wasps, which lay dozens of eggs in them. [12] The Dominican population originated from Southeast Asia but how the butterfly reached there is not known. The inner margin of the medial band is curved inwards, the outer margin is very irregular and uneven; in the cell the band does not reach the apex, but beyond the cell there are one or more cream-yellow spots, and the black groundcolour is irrorated with yellowish scales; finally at the tornal angle there is an oval ochraceous-red spot emarginate on its inner side in the female and in both sexes surmounted by a blue lunule; while in interspace 7 between the medial band and the postdiscal spot there is a large ocellus-like spot of the black ground-colour more or less irrorated with blue scales. In many butterflies and moths the eggs are laid in batches; the eggar moths often lay their eggs in masses on walls after they have been flying round lamps at night. The prolegs bear a double row of tiny hooks enabling the insect to hold firmly to the food plant. When situated among brown or dry objects, the pupa tend to turn light grey brown to pink brown and develop cryptic dark brown and black striation. Find the perfect citrus swallowtail butterfly papilio demoleus stock photo. [14], In Saudi Arabia, the highest mortality rate was found to be in larvae and pupae in cultivated populations due to a bacterium of the genus Bacillus. It can be found swarming in the groves of its food plants. This is the release. A Citrus Swallowtail Butterfly (Papilio demodocus) on red Salvia flowers. Many butterfly pupae hang head downwards by the cremaster and lack a girdle. During the rains, the adult hatches after about a week. The early instars of this caterpillar are kite shaped, and dark brown with three white patches: one on the thorax, one above the the first pairs of prolegs, and one on abdominal segments 8 & 9. Thus although most moths tend to fly at night and are dull in colour, many tropical moths tend to be brightly coloured like butterflies and fly during the daytime. The eighth and ninth segments, which earlier provided the camouflage markings now develop a brown and white band. Citrus Swallowtail Butterfly A quite large butterfly with a superficial resemblance to the Dingy Swallowtail, and sharing similar preferences for young citrus shoots to lay their much larger eggs. The parasitic wasp larvae eat the caterpillar from the inside. In this case the eggs are covered with a layer of scales detached from the abdomen of the female. With the aid of these ocelli a larva aligns itself along the leaf margin or can detect. . If the pupa is formed at the end of the rains, it may not hatch at once but remain in a dormant state called diapause during which little oxygen is used and normal chemical reactions in the body are replaced by special anaerobic ones, that is, chemical processes not requiring oxygen. Its caterpillars feed on citrus trees. Male butterflies may also produce a sex scent from special distributing scales on the wings. Photo about Citrus Swallowtail Papilio demoleus butterfly at rest, open wings. The Citrus Swallowtail (or Christmas Butterfly) has a lovely, complex pastel yellow pattern that reaches across both the fore and hindwings on the upper side. The newly emerged female butterfly is attracted to the nectar of flowers, to urine and faeces, rotten fruit and other food sources, while the mature mated female is attracted to citrus oils on the leaves on which she lays her eggs. It has a number of modes of flight. When not in use the proboscis is coiled beneath the head. Detailed description as given by Charles Thomas Bingham in 1905: "Upper side of wings has the ground colour black. The giant swallowtail, Papilio cresphontes Cramer, is a striking, wonderfully exotic-looking butterfly that is very abundant in Florida. They are the common largest butterflies in Brisbane. Lime Swallowtail Butterfly The lime swallowtail predominantly has yellow spots bordered by black with a blue eye-spot and a red spot on the lower part of the wing. Due to its capability for rapid population growth under favourable circumstances and its having been recorded to have five generations in a year in temperate regions of China, it is considered a serious potential threat. The eggs are usually spherical and cream coloured. A broad, irregular yellow band is found on the wings above, which is broken in the case of the forewing. If the barrel-shaped cuticle is broken open, a cocoon will be found inside the larval skin. Female, wing span 140mm Orchard Swallowtail Butterfly are the largest butterflies commonly seen in Brisbane. The head bears a pair of compound eyes, each with about six thousand separate lenses. After that, the caterpillar eats the leaves of the citrus tree, using its strong mandibles to chew the leaf margins. Your caterpillar is an early instar, and the coloration will change with subsequent molts. [4], Formerly absent from Borneo, it is now one of the commonest papilionids in Sabah and Sarawak in Malaysian Borneo, Kalimantan (Indonesian Borneo), and Brunei. As the larva grows, its old cuticle is shed and replaced from below by a new cuticle whose folds allow for renewed growth. The pupa does not feed. The caterpillar then moves upwards and clasps the pad with the last pair of prolegs while a girdle is spun to support the upper end of the larva when it releases its hold on the stem. The Butterflies of Australia website has images of the caterpillars and the adults. However, some major differences do occur.
