Moths at Withymead

Norman Hall and Paul Black led a moth-trapping event at Withymead Nature Reserve on the night of Saturday 25 June. Withymead is on the north bank of the River Thames between Goring-on-Thames and South Stoke. A number of members came along at 9am next morning to view the catch. The event was very successful despite the drop in the temperature over the previous few days and the increasingly high wind speeds during the daytime. The number of macro species of moth recorded (81) was surprisingly high for the conditions, especially as numbers of individual specimens were quite low. The number of micro species recorded (17) was however disappointingly low, as well as the number of individuals.

On arrival on Saturday evening, Norman and Paul had been welcomed by warden Pete Morton. They decided that they would both set up their traps and sheets on the east (railway) side of the lane, where there is good chalk flora, an orchard and a surprisingly good variety of native trees, plus the possibility of some good marshland species spilling over from the river side. One member came in the evening to watch the trapping and returned the following morning to view the catch. Other spectators on the Sunday morning included an enthusiastic 9-year old girl.

The catch included 5 species of Hawk-moths, including a Pine Hawk-moth and 5 huge Privet Hawk-moths, a Festoon (a nationally scarce oak feeder in the family Limacodidae, of which Festoon and Triangle are the only British species), a Vestal (which is a migrant), a Brown-tail (which can be a serious pest if breeding conditions are right for it) and Dotted Fan-foot, Southern Wainscot and Obscure Wainscot, all three of which might have come up from the marshy ground nearer the river.

Sample moths of all the species seen had been potted up or put in glass tubes for examination, and there were better opportunities for photography as these were eventually released. Afterwards, the warden invited members to have a look round the main part of the reserve near the river, and several of them were delighted to see a Grass Snake.
