Mating pair of Red Soldier Beetles

Family: Cantharidae Size: Body length 12-16mm Description: Head and thorax rust-red, elytra shading to a dark base, females are larger than the males When to see them: Adults are seen mostly during July & August Habitat: Often seen on umbellifer flowers such as hogweed & cow parsley, but turn up wherever there is suitable prey, nectar or pollen Food: Small insects & other invertebrates, also eat nectar & pollen.

Behaviour: The beetles make short flights between plants and may also be seen flying amongst long grass.

They move quickly over flowerheads and leaves of plants hunting for small insect prey such as aphids. They are frequently noticed as mating pairs.

Click beetles: family Elateridae

Slender and often rather downy, these beetles have the ability to spring into the air and right themselves if they fall onto their backs. They do not always land the right way up but they go on leaping until they do. the action is accompanied by a loud ‘click’, from which they take their name.

SULPHUR BEETLE – cteniopus sulphureus

Sulphur beetle-Cteniopus sulphureus

Sulphur beetle-Cteniopus sulphureus -Bryn Euryn

Family: Tenebrionidae ( sub-family Alleculinae ) Size: Body length 7-10mm Description: A distinctive bright yellow beeetle with a darker head, legs and thorax When to see them: Adults are seen mostly during May-August Habitat: Abundant on sunny well-drained grassland Feeds on: Pollen of various flowers

The Sulphur beetle is the only bright yellow beetle found in the UK  and is typically found in very dry habitats; including chalk or sandy grassland in parts of southern England. In northern England, the sulphur beetle is largely restricted to areas coastal sand dune.

Sulphur beetles are small, but they are relatively easy to spot with their yellow colouring contrasting with the flowers of their favourite umbellifer flowers. These attractive little beetles live on the flowerheads of plants such as Wild Carrot and Wild Thyme, feeding on the nectar and pollen, and are often locally abundant.

The larvae are rarely seen: they feed on the ground on decaying wood and plant material.

family-Oedemeridae

SWOLLEN-THIGHED BEETLE-Oedemera nObilis

Family: Oedemeridae Size: Body length 8-10mm When to see them: April to September. Habitat:Flower meadows, gardens and waste ground where they visit flowers. Feeds on: Pollen of various flowers Distribution: Widespread from southern England northwards to the Wash and north Wales, but less common further north than that.

Quick identification: The green elytra are pointed and gape apart. The male and female of this beetle can easily be told apart, as the male has large green bulges on its thighs, while the female does not.

The male is unmistakeable but the female could be confused with other Oedemera species, however its size, gaping wing cases and irredescence distinguish it.

Leaf Beetles: family Chrysomelidae

Most of the beetles in this huge family are smooth and shiny, with rounded outlines. Many are brightly coloured. The tarsi have 5 segments, but the 4th segment is tiny and more or less hidden in the enlarged 3rd segment. This feature should distinguish the leaf beetle from the ladybirds and all other superficially similar beetles. Almost all adults and larvae eat leaves and many species are serious agricultural and horticultural pests. The larvae are soft and slug-like and move very slowly on short legs. There are over 250 British species.

Cryptocephalus hypochaeridis

160604-BE31-Shiny emerald beetleFamily: Chrysomelidae Size: Body length 5mm When to see them: May to August Habitat: Grassy places, where the beetles commonly sit on the flowers of hawkweeds & other yellow compositae Feeds on: Pollen of various flowers Distribution: Widespread from southern England northwards to the Wash and north Wales, but less common further north than that.

I haven’t come across a common name for this beautiful little beetle. The generic name ‘Cryptocephalus‘ refers to the fact that the head of this extremely shiny emerald green beetle & its relatives is completely hidden under the pronotum.

Ladybirds: family Coccinellidae

The ladybirds are among the most familiar and best-liked of the beetles, perhaps because of their bright colours and their aphid-eating habits of most species, although not all are predatory.

7-SPOT LADYBIRDCocinella 7-Punctata

The most common ladybird in the UK

The most common ladybird in the UK

The adult is less variable than most other ladybirds and the black spots rarely fuse together, although their size may vary a good deal. It is one of our commonest ladybirds, found in most habitats.

The larvae are blue/grey in colour, resembling those of many other ladybirds; they feed on aphids.

Longhorn beetles:family Cerambycidae

Most of these beetles have fairly slender bodies and very long antennae, those of the males often being longer than their bodies.

Strangalia maculata

150712TG-Bryn Euryn-btl-Strangalia maculata (7a)This beetle superficially resembles the Wasp beetle, but has much more yellow on the elytra .

Seen from May to August and most often seen on flowers in hedgerows and along woodland margins. The larvae develop in a wide range of timber.
