August 2019 moths Hollesley

This month has not been especially exciting, though there have been a few highlights. The month started reasonably well following a hot July but most of the summery moths disappeared following the rain and wind during the second and third weeks of the month. There has been a slow trickle of routine immigrants plus some highlights amongst them too.

On the local species I had two Butterbur early in the month which is a good sign for the local population. A Rest Harrow on 8th suggesting they are resident now. A Brick on 29th was my first of what I call the true autumn species to start the autumn off. I had an unusual number of Eucosma tripoliana around the middle of the month. It is quite late for them. I was out on a PoMs trip on the Butley Estuary around then and was paddling the high tide over the salt-marsh so that made me think that perhaps they wander inland when high tides force them off the salt-marsh. Moths of interest included a Hellinsia carphodactyla on 18th which was not my first at home as I caught one several years ago. A dark form of Elophila nymphaeata that had me struggling for an identity for a while and a very small dark Caryocolum which dissected as alsinella but lacked any clear white patches quite unlike others I have seen. A few second broods have turned up. White Ermine on 27th, Chrysoteuchia culmella on 27th and the first of a number of Evergestis limbata on 24th.

Immigrants have been regular at a low level. There have been four highlights from my point of view. A Three-humped Prominent on 1st was a new species for me. I have taken three Beautiful Marbled this year and whilst it has been having a very good year as an immigrant Matthew is of the opinion that it is also resident locally. I took a Tuta absoluta on 7th. I did not take one last year and on 31st I had an Apomyelois bistriatella in perfect condition. I have seen this species in the Tangham Forest in mid-June. Sterling, Parsons and Lewington express the view that late examples of this species may be immigrants and I support this view for my specimen as the suitable habitat is not local to my home and it was caught in the front garden trap that faces the coast. In this Painted Lady year I have also had two Painted Ladys and one Red Admiral in the traps.
