Hawthorn Shield Bug
Acanthosoma haemorrhoidale
The hawthorn shield bug (Acanthosoma haemorrhoidale) is a common European shield bug. Its chief food is haws, the fruit of the hawthorn tree, but adults can overwinter on a diet of leaves, and individuals can be found on many potential food plants, including pedunculate oak, sessile oak and whitebeam. They may grow up to 17 mm (0.67 in) long, and are camouflaged in shades of green and brown. Like many so-called "stink bugs", they may release unpleasant odours when disturbed.

Range & habitat
The hawthorn shield bug is found across Europe, from Portugal to Russia, and is common in the southern part of Great Britain. Its distribution appears to be spreading north, being reported as far north as Manchester only in 1892, but having now extended its range to Northern England and even the Scottish Highlands. In Britain and North Western Europe the species is generally active between the months of April and October, although specimens can reappear from hibernation during periods of unseasonable warm weather in the winter. The hawthorn shield bug is a distinctive species, but could be confused with the birch shield bug, Elasmostethus interstinctus.
