The wingspan of the male is 30–32 mm and the female's wingspan is 35–37 mm. Antennae of male bipectinate (comb like on both sides) whereas female has filiform (thread-like) antennae. Male is about 10–12 mm in length and female is 12–14 mm in length. Pupa light reddish brown.[4]

Bionomics

The caterpillar is known to feed on Ricinus communis,[5] Acacia nilotica, Tamarindus indica, Nerium oleander, Chrysanthemum, Moringa oleifera, Ziziphus mauritiana, Cinnamomum camphora, Terminalia tomentosa, Erythrina fusca, Erythrina variegata, Eugenia, Mangifera indica, Manihot esculenta, Morus, Pithecellobium dulce, Sesbania grandiflora, Terminalia tomentosa, Ziziphus jujuba and Ziziphus mauritiana.[6] and recently from Sesbania sesban.[7]

During February and March 2002, a severe outbreak of castor hairy caterpillar was observed on acacia trees in Thailakulam, Virudhunagar, Tamil Nadu, India. Larval swarms persisted for 10 to 15 days in vegetation and were a nuisance to the environment and surrounding villages.[8] A hymenopteran Aholcus euproctiscidis is an egg parasite of the castor hairy caterpillar.[9]

gollark: The only important constraints I know of is that the OC relay must be directly adjacent to the computer (unless you program around this) and that you can't connect to the top of the 3D printer.
gollark: I think it's just that you can't connect stuff to the top.
gollark: Move items in and out, yes.
gollark: I don't think you can *use* it directly with just plethora.
gollark: The actual relay block, not a software thing.
