This larva (caterpillar) was found feeding on leaves of Nandi Flame, Spathodea campanulata, Nairobi, Kenya. Dec. 2015.

All moths and butterflies have four life stages, each with its own distinct appearance and habits. Linking each stage that might be found in an environment requires that the species be ‘reared out.’ Ideally one captures an adult female moth or butterfly, obtains from her a set of eggs, rears the hatching larvae (caterpillars) on the correct host plant, providing for the proper place for the mature larva to pupate and undergo metamorphosis (often in a cocoon or chrysalis) to the adult. When each of the stages is described and thus linked, the life history of the moth or butterfly is the result. For some species this process could take as long as a year and requires careful dedication by an observant naturalist. It is valuable work that a citizen scientist can contribute. Many, many species of African insects have incomplete or no life history information.

This larva is defended by virtue of urticating hairs. On contact with the skin pieces of the hairs break off and begin causing intense itching or dermatitis. The black and white pattern is a warning for birds and other insect eaters.
