The African comet moth (Argema mimosae), also known as the African moon moth, is a large and striking silk moth native to sub-Saharan Africa. This species is famous for its vibrant green or yellow wings, adorned with eye-like markings, and its distinctive long, tail-like extensions, which can help confuse predators. Adult moths have a wingspan of up to 15 cm, with males possessing longer tails and more angular wings than females.
The caterpillars of this species are some of the most spectacular we've seen - they feed on various host plants, several of which are easily used for rearing in captivity. Adults, like almosy all silk moths, do not have functional mouthparts and rely on energy stored from their larval stage. Their primary purpose as adults is reproduction, and their lifespan is typically brief, lasting only a few days to a week, though females can live for up to three weeks by remaining stationary whilst they wait for a mate to find them.
Like the moths, caterpillars are either bright green or yellow in colour. The caterpillars enjoy some additional warmth, e.g. a warm room or cupboard, although this is not necessary in the summer, nor is it necessary for cocoons which are very tough and resilient. If you have not reared these before, I highly recommend trying them just to see the caterpillars! Cocoons are very easy to hatch out, simply requiring a daily misting, though patience is sometimes required as they can remain in this stage for several weeks or even months if temperatures or humidity are unsuitable!
Host plants: Eucalyptus, Sweetgum (Liquidambar), Smokebush (Cotinus), Euphorbia; others reported.
Difficulty: Caterpillars are straightforward to rear (4/10); Cocoons are very easy to hatch (1/10)
Temperature: Room temperature or warmer (20-26 degrees).
Lifecycle: continually brooded; cocoons can go dormant.
