Damsel bugs

Himacerus mirmicoides

Ant damselbug

As a nymph, this predatory bug mimics an ant so convincingly that pale bands on its early body segments create the illusion of a narrow ant like waist.

WhereDry open grassland and low vegetation
Size7 to 8 mm body length
WhenApril to October

This slim predatory bug has a brown body, partly developed wings and a black connexivum marked with orange red spots along the abdomen edge. Young nymphs closely resemble ants, with pale bands across the early body segments creating the look of a narrow, ant like waist that fades as they mature.

Adults hunt small insects among low vegetation and on the ground, remaining active in most months of the year, with mating and egg laying in spring and a new generation of adults appearing by late summer.
