This primarily Asian genus (with one member in Europe) now counts 21 species. The Brahmaea or owlmoths, as they are often called, are in general fairly easy to rear, with some exceptions though. Brahmaea europaea is a bit less easy, but don't worry, it's not at all impossible to keep them alive.
Caterpillars within this genus grow large and are quite spectacular with long, fleshy scoli (those dreadlocks) in the early stages that disappear entirely after the last molting.
The members of this genus feed on Oleaceae, especially Ligustrum species. The species from the cooler regions have one or two flights annually and overwinter as pupae, which can be stored in the fridge. The more tropical ones may brood almost continuously in captivity.
