An interesting example is the case of silk caps which cover the pupal cells of the Oriental hornet Vespa orientalis.

The Oriental hornet Vespa orientalis, is a hornet which looks very similar to the European hornet.

Other temperate species (e.g. the yellow hornet, V. simillima, or the Oriental hornet, V. orientalis) have similar cycles.

A 2010 study by researchers at Tel Aviv University discovered that the Oriental hornet (Vespa orientalis) converts sunlight into electric power using a pigment called xanthopterin.

It has been suggested that the Oriental hornet uses xanthopterin as a light-harvesting molecule to transform light into electrical energy, which may explain why the insects are more active when light intensity is greater.

With the crew will be two Japanese carp, four South African clawed frogs, 180 Oriental hornets from Israel and 7,600 fruit flies, all of which are subjects in experiments on the effects of near-weightlessness on biological organisms.
