Habitat
These butterflies inhabits a range of habitats, but especially occur at the edge of rainforest or plantations and in the coastal mangrove areas.[3]
Description
Ideopsis vulgaris has a wingspan reaching Шаблон:Convert.[4][5] This butterfly is quite similar to the dark glassy tiger (Parantica agleoides). A transverse black bar in the forewing cell, cutting through one of the white streaks, distinguishes the blue glassy tiger from the other one.[4] As other milkweed butterfly it is mimicked by Chilasa clytia (Papilionidae).
Upperside: black, the dorsal margin of hindwing broadly cinereous; both wings with the following subhyaline bluish-white streaks and spots.
Forewing: a short streak along dorsal margin, two broad streaks united at base in interspace 1, the upper one curved, a broad streak in cell with an outwardly indented detached spot beyond it in apex, a slender costal streak, two large discal spots inwardly pointed, outwardly truncate, three elongate spots beyond apex of cell and four or five elongate preapical spots beyond them, finally a subterminal and a terminal series of spots decreasing in size towards apex of wing.
Hindwing: elongate streaks in interspaces 1 a and 1 b, two in interspace 1, two in cell with a short slender streak-obliquely between their apices, shorter streaks radiating outwards in interspaces 2–6, a sub-terminal series of small spots and a terminal row of dots beyond.
Underside: similar, the markings better defined. Antennae black, palpi black above, bluish white below; head and thorax black, spotted with bluish white; abdomen brown above, sullied white below. Male without any special sex-marks on the wings.[6]
Race exprompta, Butler (Sri Lanka). Closely resembles D. vulgaris Butler, but has all the markings much broader, the apical spot in cell of forewing outwardly less emarginate; on the hindwing interspaces 1 a and 1 b are entirely filled with the white streak, while the short slender streak lying between the apices of the streaks in the cell coalesces with the lower one.
Race nicobarica, W.-M. & de N. (Nicobar Islands). Like the preceding race, but the subhyaline markings still broader and somewhat blurred. Upperside: forewing: the whole basal two-thirds of interspace 1 bluish white, enclosing a fine longitudinal black line; streak in discoidal cell vary broad, occasionally produced to the apical spot in the cell. Hindwing: the black in interspace 1 reduced to a mere streak; cell entirely bluish white, traversed longitudinally by a faint black forked line. In the solitary specimen of the male in the collection of the British Museum this line is entirelyabsent.

Biology
Adults can be found all the year around.[7] They frequently visit flowers for feeding.
Females lay white eggs similar to a rugby ball. These eggs take about 3 days to hatch. The caterpillars are white with a black head, while the 2nd instar caterpillars are dark wine red to dark purplish brown colored, with whitish spots and a length about Шаблон:Cvt. In the 5th and last instar caterpillars reach Шаблон:Cvt.[4]
Larvae feed on Gymnema species (Asclepiadaceae),[4] Tylophora fleuxosa (a climber typical of mangrove areas),[4] Tylophora tenuissima (Apocynaceae) and is thus distasteful to birds.[1]
The pupa is bright yellowish green, with a length of Шаблон:Cvt. After about 7 days the butterfly emerges.[4]
