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.
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.
This moth, so well camouflaged on the oak trunk, has recently emerged, having spent the winter as a pupa underground. The caterpillars feed on oak leaves, so this species is not uncommon in the Wyre Forest.
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
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!
The toads have been busy laying their spawn in various places in and around Wyre. Their strings of eggs are wound round water plants and each string contains about 1500 eggs.
After many days of rain, mist and gloom, the sunshine and blue skies on Saturday 14th April 2018 were welcomed! Nature responded and the air was filled with birdsong and the buzzing of bees, and many flowers opened. On the roadsides in Bewdley Lesser Celandines and Daisies were out in profusion – a celebration of spring.
Yesterday Wyre Forest Study Group members braved the cold rain and ventured out into Earnwood Copse, following an ancient sunken track down through the woodland. 2 micromoths Diurnea fagella were spotted on tree trunks, as was the attractive harvestman Megabunus diadema. A Larch Ladybird and spiders Diaea dorsata were found in conifers, and down at the stream water crickets Velia caprai were swimming around on the water surface in the eddies. In open areas near the stream Opposite-leaved Golden Saxifrage was flowering well. But the Sallow catkins were still closed, waiting for warmth and sunshine.
A late night walk in the snowy garden with a magnifying glass enabled me to see some detail in the snow flakes – what lovely patterns there are!
Elfcups are spring cup fungi that brighten our late winter woodland floor with their attractive fruiting bodies. They grow, often in troops, on rotten fallen twigs of broad-leaved trees. Previously thought to be one species, it has recently been discovered that there are two, only separated by details of the spores. Scarlet Elfcup (Sarcoscypha austriaca) appears to be commoner than Ruby Elfcup (Sarcoscypha coccinea).
