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 male caddisfly, which lives in the River Severn, has very large maxillary palps which look like boxing gloves!
This snail, about 19mm in size, is not commonly found within the forest, but does occur in some damp meadows and along the banks of the River Severn. The shells have a distinctive brown line and mottling, there is a white band around the lip, and the umbilicus on the underside is completely covered over. The body of the snail is typically black as seen in this photograph. These snails do not reach maturity until they are between 2 and 4 years old.
The banks of the River Severn are colourful with flowers at present – comfrey, red Campion, Garlic Mustard, Cow Parsley and others. Much of the comfrey we see locally is Russian Comfrey Symphytum x uplandicum which is a hybrid between Common Comfrey (Symphytum officinale) and the introduced Rough Comfrey (Symphytum asperum).
An early morning walk along the river bank gave me good views of this Song Thrush and Robin collecting food for their young. The thrush was so engrossed in its task it allowed me to get within a few feet of it.
A walk on the west side of the River Severn yesterday near the Bewdley bypass resulted in the find of two female Yellow-legged Water-Snipeflies (Atherix ibis). They are impressive flies with their mottled wings and they have interesting breeding behaviour. The females gather together in dense clusters on branches overhanging water where they lay their eggs in a glutinous matrix before dying. The result is a mass of eggs and dead flies suspended from twigs or flood debris.
The Grey Seal spent Sunday 13th January 2013 in Bewdley. During the morning she was seen up near the Dowles Book confluence and at lunchtime she was watched dodging the boats out practicing from the rowing club. I heard someone shout to one crew – “You’ve just run over a seal!” She swam down to Bewdley quay where several startled onlookers saw her catch a Mallard drake, which explained why the birds had been looking so agitated as she swam past! She stayed in Bewdley town for a couple of hours before disappearing downstream at about 14.00.
