Tortoise Bug - Eurygaster (cf) testudinaria

Length 9 to 11 mm. A fairly large shieldbug, the two Eurygaster species are often known as Tortoise Bugs. The ground colour and intensity of the markings are variable. This species is distinguished from the slightly smaller and rarer E. maura by the slight central depression at the front of the head and the slightly more protruding hind corners ('shoulders') of the pronotum. These characters are not always reliable; genital examination may be necessary.  Because it requires genital examination to eliminate E. maura and it is unlikely that our recorders will have gone to such lengths, we have designated this species as Eurygaster (cf) testudinaria.

Dry and damp grasslands.

Adult: All year

Nymphs feed on grasses between May and August, becoming adult from July.

Previously uncommon, it is now widespread in southern Britain and Ireland in and is expanding its range northwards.
