Biosonar Turns Waspish

Nature (7228, p.361) had notice of an article in Biological Journal of the Linnean Society (96, 82-102, 2009) that demonstrates the use of biosonar in several species of parasitic wasps. These wasps seek out beetle larvae in trees, using hammer-like ends of the antennae to produce sound.

So far as I know, this is the first group of invertebrate species to be shown to use biosonar.
