Chalcid Wasp

Brachymeria sp.


Chalcid wasp about 6 mm long, dark brown with a rugose thorax and yellow hair on the abdomen. Enlarged hind femora with a yellow band. Family Chalcidae. These little wasps are parasites of lepidopteran larvae (emerging from the pupae) and of flies parasitic on other insects. Many species are prime candidates for biological control of pest species.


Landed on a lighted window at night, small store, Axtla de Terrazas, Xilitla, San Luis Potosí.

HI Lauren
What a lovely little wasp. Probably a Brachymeria - but looks not quite so typical so it might be something else.
