Small Purple and Gold Pyrausta aurata

This pretty little daytime-flying Crambid micro-moth is often seen flying around mint, marjoram and related plants. There are 2 broods between May and September, and they can be found in gardens where the caterpillar foodplants are grown. They look very like the Common Purple and Gold Pyrausta purpuralis which has more yellow markings on the wings, is a little larger, and which may also be found in Wyre, breeding on thyme and Corn Mint.

Dark Green Fritillaries

Craig Reed photographed these lovely Dark Green Fritillary butterflies in Wyre recently. This species was first recorded in the Forest a few years ago and they are now breeding annually. The females use scent to locate violets on which they lay their eggs. When the caterpillars hatch they immediately go into hibernation and only start to feed the following spring, leaving characteristic moon-shapes holes in the violet leaves. They can sometimes be seen basking nearby.

Marbled White (Melanargia galathea)

Marbled White butterflies are now on the wing in some of our meadows, the males gliding over the flowers in their search for females. They live in colonies and breed where the grass is long, eggs being dropped amongst the vegetation. The tiny caterpillars emerge in August and overwinter before feeding and growing the following spring. They eat grasses, especially Red Fescue in the early stages. This butterfly has expanded its range northwards in recent years and was first recorded in the Wyre Forest in 1997. This newly emerged adult was seen roosting on Red Clover at 7.00pm.

Peppered Moths (Biston betularia)

The commonly found Peppered Moths are a well-known example of Darwin’s natural selection. They are normally white with black speckles which enable them to be well camouflaged on lichen-covered trees in rural areas, unlike the naturally occurring melanic black form which are more readily predated. However, in places where there is more air pollution and less lichens, the black form predominate. Now we see both these colour forms and and intermediate one too.

Pearl-bordered Fritillaries, Boloria euphrosyne

These lovely butterflies are now on the wing and flying in sunshine. Their caterpillars need violet plants on which they feed, but the adults nectar on a variety of flowers, especially Bugle. They were close to extinction in Wyre in the early 1990s, but ongoing conservation management by Butterfly Conservation, the Forestry Commission and English Nature to open up sunny sheltered areas has halted their decline and resulted in increased numbers.

Caddisfly first for Wyre Forest

Trichostegia minor - a Caddisfly- 26 April 2018-Mike Averill

This caddisfly larvae Trichostegia minor is the first record for this species in Wyre and was  found in the new Helen Mackaness Reserve. It is usually found in ponds and ditches in woodland and so always likely to be found in Wyre. The adult emerges in June-July and is a mottled brown colour

Glowworm larva!

It was great to see a Glowworm larva walking across the track in Wyre recently. Larvae are usually nocturnal, but in their third year, between April and June, they start to wander around both in the daytime and at night prior to pupating. We look forward to seeing the adult females glowing after dark in June and July…if we can stay awake that late!
