Pine Processionary

A grey moth whose caterpillars march in long nose-to-tail processions between their silk nests and feeding sites. The larvae's urticating hairs cause severe allergic reactions.

Black Soldier Fly

A large, wasp-like fly with a shiny black body and translucent areas on the abdomen. Its larvae are extraordinarily efficient at converting organic waste into protein and fat.
