- They lay one egg on insect larvae and the young wasp consumes the host larva from the inside as it undergoes development.
- Professor Ilari Sääksjärvi of the University of Turku said that the ovipositor of Dolichomitus meii is very long.
- The wasp sticks its ovipositor through a hole in the wood and attempts to find host larvae.

- Birds do not eat the wasp sitting on a tree trunk because they think it does not taste good or that it is dangerous to eat.
