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.
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.
Whilst out in the Forest yesterday Dave Scott spotted this Grey Shoulder Knot on the bridge near Lodgehill. Roger Plant’s excellent photograph of the moth sitting on grey lichens demonstrates its amazing camouflage!
2 Pyrausta daytime-flying pyralid moths can be seen in Wyre during the summer. Pyrausta aurata, the commoner of the 2, can be found in gardens too where the caterpillars feed on mints, marjoram and other labiates. Mick Farmer spotted this one in Bewdley. The larvae of Pyrausta purpuralis feed on wild thyme and mints in Wyre.
One male Red-tipped Clearwing moth was attracted to a pheromone lure in Bewdley this week, near the river below the Bewdley bypass bridge. Clearwings were rarely seen before pheromones were developed. These are artificially produced chemicals which are very like the pheromones produced by the female moths, and so they attract the males. All clearwing moths are daytime flyers, but are easily overlooked as they can look like wasps when they are flying.
This migrant daytime flying moth arrives in Britain from southern Europe and northern Africa from April onwards. It can be seen hovering in front of flowers from which it feeds with its long proboscis. Eggs are laid on Ladies Bedstraw, Madder and Hedge Bedstraw and caterpillars may be found between June and October. Mick Farmer did well to capture this photograph of the moth feeding.
The December Moth flies between late October to early January. The adults come to light and can sometimes be seen in the morning on house walls when lights have been left on overnight. The female lays her eggs on the twigs of broad-leaved trees. The overwintering eggs hatch in April when the caterpillars feed on the buds and new young leaves.
Buff Tip moth eggs are laid in batches on various deciduous tree species. The caterpillars feed gregariously in the summer and often defoliate whole branches. The ones shown here are feeding on Hornbeam.
The Mocha moth visited Oliver Wadswoth’s light trap on the Study Group’s evening meeting on 20th August 2016. This is a new moth species for Wyre so we were all very pleased to see it. The larvae feed on Field Maple which only occurs occasionally within the Forest.
This beautiful and impressive moth is on the wing this month. The larvae live inside small branches of various deciduous trees, taking up to 3 years to mature. The adults are nocturnal and cannot feed, so need to reproduce speedily when they emerge. The males (as seen here) have impressively large comb-like antennae so that they can pick up the pheromone scents of emerging females. These moths are attracted to light but can sometimes be seen during the daytime resting on tree trunks.
