Top 20 Most Common Insects in Mymensingh

Yellow paper-wasp are known for their intriguingly vivid yellow coloration, an uncommon characteristic among wasp species. Their unique thermal regulatory system allows them to thrive in varying climates. Yellow paper-wasp's contribute significantly to the ecosystem through their role as pollinators and as preying on certain insect pests. Moreover, their complex social structures showcase some of the animal kingdom’s most fascinating manifestations of cooperative behavior.

Male. Upperside rufous-brown. Forewing with three semi-hyaline small white sub-apical spots from near the costa, the middle one the smallest and well inwards; in some examples one or both of the lower spots are absent; a large semi-hyaline spot inside the cell, near its end, its inner side square, its outer side deeply excavated, with a small spot between it and the costa, a small round spot near the base of the second median interspace, a much larger round spot in the middle of the first median interspace, and a minute spot (sometimes two) below them in the middle of the interno-median interspace, all these spots slightly tinged with ochreous, and varying much in size in diticrent examples; sometimes the large excavated spot in the cell is split into two, sometimes represented by a small round spot immediately below the sub-costal vein near the end of the cell, and sometimes it is entirely absent; there are some brownish indistinct marks on the wing, one in the interno-median interspace before the middle, a series of conjoined discal marks and an indistinct outer marginal band. Hindwing with a brown spot at the end of the cell, a discal brown macular band, corresponding in its curve to the outer margin, and a marginal band. Cilia of both wings brown. Underside like the upperside, but duller in colour. Forewing similarly marked. Hindwing with the brown bands somewhat more distinct, the cell spot with a brown spot on each side of it, and a sub-basal brown spot. Female similar to the male.

Males and females upperside white, in many specimens pale ochraceous yellow, veins black. Forewing with four very slender irregularly sinuous transverse black lines, the costal margin shaded with ochraceous at base and fuscous beyond; cell crossed by three or four additional short lines; a postdiscal very incomplete series of white-centred broad fuscous rings in the interspaces, tinged with ochraceous near the tornus and broadly interrupted in interspaces 3 and 4; beyond this two transverse black lines not reaching the dorsal margin, shaded with fuscous between; the apex broadly and the termen also shaded with fuscous. Hindwing with three transverse fine lines; a pair of postdiscal broad black lines shaded with light sepia brown between, forming a conspicuous band, the outer line broken and incomplete, followed by two irregular black lines, a subterminal more pronounced black line, and posteriorly a narrow black terminal margin; dorsal margin broadly fuscous at base; apical half and the tornal area and lobe rich ochraceous, with some sepia-brown and black markings. Underside similar, the markings of the upperside showing through by transparency; the ochraceous shading on dorsum and tornal area on hindwing of less extent, but the tornal lobe darker ochraceous with a central large round black spot. The markings both on upper and undersides vary a little in depth of colour and breadth. In many specimens there is a diffuse fuscous spot between the discal pair of transverse fine lines on forewing. Antennae, head, thorax and abdomen above black, thorax and abdomen with lateral greyish longitudinal stripes: beneath white. Body of the female paler than that of the male. Expanse 6 - 7 cm. The eggs were curious and beautiful, high domed-shaped or almost conical, with an aperture at the top fitted with a deeply dentate flat cap like a cogged wheel. The larva was unlike any other that, we have ever seen, slender, cylindrical and smooth; with two long curved divergent filaments or soft horns on the head, a single at outer sword-shaped one on the back at the 5th or 6th segment curved backwards and serrated on its inner edge, and another on the last segment curved forwards and serrated on its outer edge. The colour was a fine reddish brown with a broad green band on the side from the 5th to the last segment. The pupae were suspended by the tail, very much compressed, with a dorsal ridge from head to tail, high and obtusely pointed in the middle, the palpi-cases united and produced into a long somewhat recurved snout; colour brown with fine dark striae.

Cethosia cyane, the leopard lacewing, is a species of heliconiine butterfly found from India to southern China (southern Yunnan), and Indochina. Its range has expanded in the last few decades, and its arrival in the southern part of the Malay Peninsula, including Singapore, is relatively recent.

Remelana jangala is a butterfly in the Lycaenidae family. The scientific name of the species was first validly published in 1829 by Horsfield.

Parnara ganga, the continental swift, is a butterfly belonging to the family Hesperiidae. It is found in India and south-east Asia, including Vietnam.

Nausinoe perspectata is a moth in the family Crambidae. It was described by Johan Christian Fabricius in 1775. It is found in the Democratic Republic of the Congo, China, India, New Guinea, Sri Lanka, Taiwan and Australia. The larvae feed on Jasminum sambac.

Its wingspan is about 40 mm long. The abdomen is yellow. Antennae black with a scarlet basal joint. Palpi scarlet at sides, white below, the terminal joint black. Head white with a crimson line behind it. Thorax white. Wings primarily white. Forewings with a scarlet fascia along the costa. Red markings are with a deep crimson tone. The band on the head is broader. A black speck at each angle of cell present, but some absent. Hindwings with a black spot at end of cell and a sub-marginal series of four, the two towards anal angle sometimes absent. Larva black with lateral tufts of reddish-brown hair. A sub-dorsal series of scarlet spots present. Dorsal, sub-dorsal, and lateral series of black spots also present. Somites 1st, 3rd, 4th and 5th with sub-lateral spots. Two spots only on the 11th somite.
