Centrotus cornutus-treehopper-Bury Ditches hill Fort- Clun

Centrotus cornutus
Family: Membracidae

One of only two UK treehoppers, C. cornutus can be found locally on a range of plants in woodland rides and similar habitats.

The other species, Gargara genistae is associated with broom. It is smaller than C. cornutus, lacks the horn-like projections on the pronotum and has a shorter dorsal spine.

Adult: April-August
Length: c10 mm.. UK BUGs

Cercopis vulnerata Red-and-black Froghopper (RSPB Lakenheath)

Cercopis vulnerata Red-and-black Froghopper
Family: Cercopidae

A truly unmistakable species, and one of our largest homopterans. The nymphs are rarely seen, as they feed on underground roots.

Adults are found in mainland Britain south of the Scottish Highlands, in a variety of wooded and open habitats.

Adult: April to August
Length 9-11 mm

Eurydema oleracea Brassica Shieldbug (RSPB Lakenheath)

Eurydema oleracea Brassica Shieldbug
Family: Pentatomidae

Species of Eurydema are dramatically coloured, usually red and black bugs, but often with other colour morphs. In E. oleracea the dark metallic green/blue-black ground colour is overlain with red, yellow, cream or orange markings.

This bug overwinters as an adult, emerging in the spring. Larvae, which are similar to those of the rarer E. dominulus, may be found May-July on a range of hostplants in the Brassicaceae. These include jack-by-the-hedge, garlic mustard and horse-radish. Well distributed in southern and central England.

Two adults and a first instar just in show to the left.

Enoplops scapha Boat Bug
Family: Coreidae

A large and distinctive dark grey squashbug with cream markings on the connexivum. Early instar larvae have very spiny antennae and a green abdomen. Later instars are superficially similar to the much commoner Coreus marginatus but the abdominal tergites are more pointed.

A local species which is mostly confined to coastal areas between Kent and north Wales, favouring dry open habitats such as sand dunes and soft cliffs. The foodplant is scentless mayweed and other Compositae….British Bugs

Stenodema calcarata (St Davids)


Stenodema calcarata
Family: Miridae

Stenodema species are elongate grass bugs with a longitudinal furrow between the eyes. The genus is best distinguished by the coarsely and densely pitted pronotum, although the two spurs on the hind femora of S. calcarata make this species unmistakeable. S. trispinosa has three femoral spurs.

Common throughout the UK, both adults and larvae feed on the unripe grains of a number of grasses, although this species is often commoner in drier habitats than S. laevigata.

This bug overwinters as an adult and emerges in April, following which females turn green while males remain mostly straw-coloured. Late-instar nymphs have a single femoral spur. The new generation is complete by August… British bugs

Heterogaster urticae -Nettle Ground Bug


Heterogaster urticae Nettle Ground Bug
Family: Lygaeidae

This ground bug is recognized by the alternate dark and light markings on the legs and connexivum; the tibiae have three dark bands. In addition, the head and pronotum are covered in long erect hairs.

Found throughout southern Britain in open habitats, and recently recorded from the north (including Scotland), this bug often forms conspicuous aggregations on nettles, the hostplant. Adults overwinter, emerging and mating in the spring, during which the sexes may remain coupled together for several days. The new generation is complete from late summer onwards.

Adult: all year
Length 6-7 mm
