Top 20 Most Common Insects in Ahmedabad

This butterfly closely resembles Appias paulina but the males can be distinguished by the more acutely pointed forewing and the females by the narrower oblique black band on the underside of the forewing. Other differences are given below. Wet-season form: Males have the upper forewings irrorated (sprinkled) with black scales at the apex and anteriorly along the termen, much more sparsely and narrower in general than in A. paulina. On the underside, the apex of the forewing and the whole surface of the hindwing are pale dull ochraceous, sometimes with a faint pinkish tint, but never pale yellow as in A. paulina. The sexes are dimorphic; the females differ as follows: 1st form: On the upperside, the posterior tornal portion of the black area on the forewing is not inwardly rounded, but straight and generally diffuse. The underside is very like the underside of the dry-season form of A. paulina female. It differs, however, in the narrowness of the oblique curved black band, the outer margin of which is irregularly zigzag, and never evenly curved as in A. paulina. 2nd form: Markings as in the 1st form, but the ground colour on the upperside is entirely pale yellow. On the underside, the apical half of the cell and the disc of the forewing up to the black band are pale sulphur yellow. The oblique curved black band is as in the 1st form and the interspace 1 is whitish. The rest of the forewing and the entire surface of the hindwing are rich chrome yellow. The antennae, head, thorax and abdomen are much as in A. paulina, but the antennae are dusky black and more closely speckled with white; the underside of the thorax is white in males, never yellow. Dry-season form: Upper and undersides: similar to that of the wet-season specimens, but in the male the dusting of black scales on the upperside has almost, in some specimens completely, disappeared, while on the underside the ochraceous colouring is much paler. In the females both dimorphs differ but little from the dimorphs of the wet-season form, only on the upperside the black on the apical half of the forewing and on the terminal margin of the hindwing is more restricted, while on the underside the oblique curved black band that crosses the forewing is distinctly narrower with a tendency to become diffuse. The wingspan is 6 - 7 cm.

The pharaoh ant (Monomorium pharaonis) is known as one of the most widespread house ants in the known world. As a vector of diseases, they are considered to be a pest when invading hospitals. In moderate clients, they are almost entirely found indoors. They are identified with their sandy appearance, but they are not shiny.

The butterfly closely resembles the monarch butterfly (Danaus plexippus) of the Americas. The wingspan is 70 to 95 millimetres (2.8 to 3.7 in). Both sexes of the butterfly have tawny wings with veins marked with broad black bands. The male has a pouch on the hindwing. The margins of the wings are black with two rows of white spots. The underside of the wings resembles the upperside but is paler in colouration. The male common tiger has a prominent black-and-white spot on the underside of the hindwing. In drier regions the tawny part of the hindwing pales and approaches white in colour making it very similar to the white tiger (D. melanippus).

Male upperside brownish purple, dark blue at base of wings. Forewing: costa very narrow along its apical half, termen evenly and a little more broadly from apex to tornus, edged with brown; the area on the disc, in the cell and beyond it is covered with hair-like specialized scales and is distinctly darker. Hindwing: similar, the brown edging to the costa much broader; posteriorly in the tornal area there is a dark spot in interspace 1 and another more clearly defined similar spot in interspace 2, both spots merged more or less into the terminal brown edging. Cilia of both forewings and hindwings white, with their basal halves evenly dark brown. Underside: greyish brown. Forewing: two short white lines, one each side of the discocellulars; a minute black subcostal dot above apex of cell, another similar dot a little beyond it; two parallel, obliquely placed, transverse, upper discal white lines, followed by an inner and an outer obliquely placed, irregular, broken, subterminal line also white, the inner one somewhat lunular, and an anteciliary dark line; the posterior third from base of the wing uniform, somewhat paler than the rest. Hindwing: the following black white-encircled spots conspicuous: 4 subbasal spots in transverse order, a subcostal spot in middle of interspace 7, two minute geminate (paired) spots at the tornal angle, and a larger one in interspace 2; two transverse short white lines on either side of the discocellulars as on the forewing; a transverse, curved, catenolated, discal band of white markings, followed by a postdiscal and subterminal series of white lunules and an anteciliary dark line edged inwardly with white. Antennae dark brown, the shafts ringed with white; apex of club also white; head, thorax and abdomen dark brown, the thorax in fresh specimens with a little purplish-blue pubescence; beneath: palpi, thorax, and abdomen white. Female upperside: rich silky brown. Forewings and hindwings: suffused with purplish blue at base, and with anteciliary black lines. Hindwing: with two black spots at tornal area as in the male. Underside: as in the male but the markings more regular, more evenly and neatly defined, and the white transverse lines on the forewing carried to the dorsal margin. Cilia, antennae, head, thorax and abdomen similar to those of the male, the thorax however, devoid of any bluish pubescence (fine hairs) on the upperside.

It is a medium sized red dragonfly with extremely long anal appendages. It can be distinguished from other species of this genus by the dark-brown hind-wing patch, not surrounded by a golden yellow areola, in the base. Female is similar to male; but may be red as the male or yellowish in color. This species reproduces in open pools, ponds and in grassy marshes. Adults are often found in bushy areas and around woodlands around them. This dragonfly is commonly seen patrolling over water bodies and open space in sunny days. Pairs in copula or in tandem can also sometimes be seen flying low above water bodies.

The male has a reddish-brown face, with eyes that are crimson above and brown on the sides. The thorax is red with a fine, purple pruinescence. The abdomen, the base of which is swollen, is crimson with a violet tinge. The wings are transparent with crimson venation and the base has a broad amber patch. The wing spots are a dark reddish-brown and the legs are black. The female has an olivaceous or bright reddish-brown face with eyes that are purplish-brown above and grey below. The thorax is olivaceous with brown median and black lateral stripes. The abdomen is reddish-brown with median and lateral black markings. The black markings are confluent at the end of each segment and enclose a reddish-brown spot. The wings are transparent with brown tips. The venation is bright yellow to brown and basal amber markings are pale. The wing spots are a dark brown and the lags are dark grey with narrow yellow stripes.

The ground colour on the upperside of the males is white, sparsely irrorated (speckled) at base of forewings and hindwings with black scales. The forewing has a small black spot on the discocellulars; apex broadly black, with an enclosed oval, curved, rich orange patch placed obliquely and traversed by the veins, which there are black; inner edge of black area diffuse. Hindwing is uniform, except for a preapical short diffuse black streak from the costa, sometimes absent, and a series of terminal black spots that in specimens from moist localities are very large. Underside is white with the cell and apex of forewing suffused with sulphur yellow, the orange patch of the upperside shows through by transparency, its inner edge margined anteriorly by a very obscure oblique fuscous band. Hindwing has the preapical short transverse black streak on the upperside obscurely indicated. The female is very similar to the male but can be distinguished as follows: Upperside of the forewing has a narrower orange patch enclosed within the black apical area; a small black spot in middle of interspace 1 and another in interspace 3. Hindwing has the terminal spots slightly larger. On the underside the apex of forewing and whole surface of hindwing suffused lightly, or in specimens from very dry localities heavily, with ochraceous. Forewing has spots in interspaces 1 and 3 as on the upperside. Hindwing: a curved, almost complete, discal series of fuscous spots; otherwise as in the male. In both sexes the antennae vary from white to pale brownish; head, thorax and abdomen black, the head and thorax with short greyish-brown hairs; beneath: the palpi, thorax and abdomen white.
