Ynghylch

Hairy shieldbugs are a common sight across much of the UK, particularly along hedgerows and at the edges of woodland, but also in parks and gardens. As the name suggests, they're covered in tiny hairs - though you may have to look closely to spot them! They are also known as sloe shieldbugs, because they're often found around blackthorns, where they use their piercing mouthparts to feed on the fruits - called sloes. They also feed on the leaves, seeds and fruits of a wide range of other plants.

Hairy shieldbugs spend the winter as an adult, emerging in spring to mate. Females lay clumps of brownish, barrel-shaped eggs that stick firmly to the chosen plant. The young, known as nymphs, are smaller and rounder than the adults, but still covered in pale hairs. They go through several stages of growth, before maturing into their adult form in late summer or early autumn.

A large, purplish-brown shieldbug with a greenish scutellum (the triangular patch in the centre of the back). It has a black-and-white chequered border at the rear of the body, and black-and-white antennae. On closer inspection, it is covered in fine, pale hairs. In winter, adults are browner, without the purple hue.
