Oberthuerella lenticularis, usda, buffington

This is picture 7 from a 12 picture invited series by Matt Buffington (matt.buffington@usda.gov) at the USDA Parastitic Hymentoptera group using specimens from the U.S. Natural History Museum Smithsonian. Matt uses a system very similar to ours to photograph and stack this super tiny wasp.This specimen of Oberthuerella lenticularis is in the USNM, and is over 100 years old! Native to Madagascar, we don't know what it uses its long ovipositor for, but we are sure its unpleasant for the recipient!
