Light micrograph of a tiny parasitoid wasp (Wallaceaphytis kikiae) viewed from above. Parasitoid wasps lay their eggs inside other insects. After hatching, the larvae feed on their host, eating it alive from the inside out. This is a new genus of parasitoid wasp recently discovered in the rainforests of Borneo, where a single female wasp was found mixed in with thousands of other insects. It measures only 0.75 mm in length and has unusual antennae, legs and wings. It’s named after Alfred Russel Wallace, who coauthored the first ever publication on evolution by natural selection with Charles Darwin and who himself identified new insects while in Borneo in the mid-19th century. Even today, Borneo is still known to be rich with other undiscovered species. — Andrew Polaszek, Natural History Museum
