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. In adult Eurygaster maura the second antennal segment is approximately twice as long as third, whereas in adult Eurygaster testudinaria the second antennal segment is less than twice as long as third segmen; genital examination may be necessary.  Because it requires detailed examination to eliminate E. maura we have designated most records this species as Eurygaster (cf) testudinaria (meaning 'likely to be').

Eurygaster maura is very similar and can only be reliably separated from E. testudinaria by genital examination. However E. maura has only been recorded from Essex, Kent, Surrey and Hampshire so specimens found in Leicestershire can reasonably be assumed to be E. testinaria. However species distributions are changing so it is possible that E. maura may expand into more northerly areas in the future.

as 'cf.'

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.
