Green Shieldbug Palomena prasina

The Green Shieldbug, commonly seen in gardens as well as the wider countryside, overwinters as an adult. Although usually conspicuously green, in the autumn they darken and become well-camouflaged as they hibernate amongst dead leaves. When they become active again in the spring, they gradually return to their green colouration.

Gorse Shieldbug, Piezodorus lituratus

Jon Cartwright photographed this adult Gorse Shieldbug on gorse at Fastings Coppice in May this year. It will have overwintered and bred this spring. Now, in July, we can find the late instal nymphs which should be mature by the end of the month. The sexually immature late summer adults have purplish coloration, but when they emerge from hibernation they are usually yellow-green.

Bronze Shieldbug, Troilus luridus

Jon Cartwright spotted this Bronze Shieldbug eating a Peacock butterfly caterpillar in Wyre recently. The adults of this species always have an orange band on the penultimate antennal segment. The young nymphs feed on plants, but the adults predate insect larvae, especially caterpillars and beetle larvae.

Woundwort Shieldbug – Eysarcoris venustissimus

At this time of the year any patch of Hedge Woundwort is worth checking for the Woundwort Shieldbug (4-7mm), although it might also be found on White Dead-nettle and other labiates. The adults breeding now have overwintered, and the new adults will be found in August.
