Damsel bugs

Himacerus apterus

Tree damsel bug

This damsel bug's wings are so short they barely reach halfway down its body, yet it remains an effective hunter of aphids and mites in trees.

WhenJune to October

The tree damsel bug is a slender, reddish brown bug with a black connexivum marked by orange red spots. Its wings are unusually short for the group, reaching only the third or fourth segment of the abdomen rather than covering it fully.

It hunts aphids, mites and other small insects on trees and bushes, with young nymphs feeding closer to the ground on grasses and herbs before moving up into shrubs and trees as they mature. It favours open woodland with grass and scattered bushes over farmland.
