Dorsal view
Ventral view

Delias acalis resembles Delias pasithoe in both sexes; the differences are as follows: Upper, forewing: the white spot at apex of cell replaced by an upper and a lower grey scaled spot that crosses the discocellulars, which are black; the postdiscal series of hastate (spear-shaped) spots converted into broad greyish diffuse streaks of which the streak in interspace 3 is shifted more inward than the others. In the rf the broad subbasal greyish streaks in interspaces 1 and 2 and in the cell are longer than in the female. Hindwing black; basal area to middle of cell deep vermilion, traversed by the black veins; interspaces la, 1 and posterior medial portion of 2 powdered thickly with greyish-white scales in the male; remainder of interspace 2 bright yellow; interspaces 3 to 8 with broad diffuse grey streaks that do not reach the termen, the streaks in interspace 5 extend into apex of cell; in female similar, but interspaces 2 to 5 with still broader yellow streaks, of which those in interspaces 4 and 5 cross over the discocellulars into the apex of the cell. Underside: similar to the upperside, the grey markings paler, almost white; hindwing in both sexes with the basal vermilion patch extended to the base of the dorsal margin: humeral angle at base of wing with an ochraceous spot; apex of cell and broad streaks in interspaces 1 to 8 yellow fading to yellowish white anteriorly: the veins narrowly black, which colour broadens triangularly at their apices and so forms anteriorly a more or less irregular terminal black margin. Antennae, head, thorax and abdomen as in D. pasithoe.[1]

Distribution

S.China;Nepal; Sikkim; Bhutan; Assam; Burma: Tenasserim; extending to Java and the Malay Peninsula.

gollark: There are almost certainly electromechanical safeties too.
gollark: It was brought on as a worm on USBs somehow.
gollark: Stuxnet wasn't done remotely. They chained together a ridiculous number of zero days to attack the computers the centrifuges were physically connected to and the PLCs.
gollark: It might be fun to use it to generate *maximally* right/left-wing text.
gollark: I would assume that would be a fairly easy machine learning classifier thingy, at least if you had enough text of known wingness to train it on.
