Taeniogonalos gundlachii

One of the smallest wasps I've seen (minus a few Ichneumonids that come to my lights at night). On Rhus copallinum at a mixed forest edge.

Finally got an ID on this solitary wasp, and WOW! Not only is it rare, but it is a hyperparasitoid. From BugGuide:


"Trigonalids are hyperparasitoids, parasitizing ichneumonid wasps and tachinid flies that are parasitoids of lepidopteran and dipteran hosts.
Females lay their eggs along the upper edge of a leaf that are then eaten by a feeding caterpillar. After ingestion of the eggs, if the caterpillar is parasitized by a primary host (a wasp or fly), upon hatching, the trigonalid larvae seek out the host larvae and parasitize them. They then emerge from the primary host puparium. (Ross Hill)"
