Sclerodermus

Sclerodermus is a genus of chrysidoid wasps in the family Bethylidae. There are at least 20 described species in Sclerodermus.

== Reproduction and sex ratios == Species of Sclerodermus exhibit quasi-social behavior: multiple females cooperate to paralyze a host and care for a shared brood. Despite this cooperation, they consistently produce highly female-biased sex ratios often with less than 10% males, even when many mothers are present.
