European Orussid Wood Wasp

A small, dark parasitoid wood wasp with a distinctly flattened head and stout build. It lays eggs into wood to parasitize wood-boring beetle larvae.

💡

Did You Know?

Orussids use vibrations transmitted through wood to locate hidden host larvae deep inside tree trunks, similar to echolocation.

Solomon's Seal Sawfly

A small, entirely black sawfly whose grayish-white larvae with black heads are highly destructive to Solomon's seal plants. Larvae feed from the leaf edges inward.

💡

Did You Know?

The larvae are so well camouflaged against the undersides of Solomon's seal leaves that gardeners often only notice them after severe damage is done.
