Common flowerbug
The common flowerbug is a common minute pirate or flower bug.
It is a predatory insect, feeding on small insects including greenfly and red spider mites. It is typically 3–4 mm in length, with reflective forewings and black pronotum. The legs are mostly orange-brown. It more commonly inhabits lower moist, shaded vegetation than trees, and especially nettles in the later half of the growing season. A. nemorum lays its eggs inside plant leaves.
The common flowerbug is found across Europe and the Palearctic to China. It is common in Great Britain and Ireland. In the Alps it is found to about 2000 meters above sea level'
It has been used as a biological pest control since 1992, primarily to control Cacopsylla pyri. It is capable of biting humans.
