Birds aren’t the only things flying in January; there are a few moths too. Today I trapped two Pale Brindled Beauties at Rye, one melanic (monacharia) and one the normal form. Both are males, as the females are wingless. Melanics were unknown in East Sussex until the 1960s but now comprise up to 5% of the population.

This is not that unusual, as the same species has behaved in a similar way over the past decade, but over the three previous winters, which have been colder, the latest records I have of this species in Northiam are in week 47 of the year, and the earliest in week 9.

Today in my trap I found this small moth of the family Tortricidae. Not recognising it, I posted the photo to the ukmicromoths Yahoo group. Majority opinion is that it is Acleris umbrana (a.k.a. Dark-streaked Button), which would be about the sixth Sussex record, all but one since 2006, so it’s another of those very recent colonists from across the Channel to southern coastal counties, nationally rare and proposed as Red Data Book Class 1. BUT, there are similar Acleris that can be highly variable, so closer examination is being arranged to confirm its identity.

It is the bee Colletes hederae, a species that was first seen in the UK in 2001, and whose spread is being monitored by the Bee, Wasp and Ant Recording Scheme (BWARS).  They are interested in studying the progress of this attractive bee as it colonises the UK. 

They can also be observed on bare ground where they make their nests.  With broad pale bands on the abdomen this is the only solitary bee that is likely to be flying now, so identification is not too problematical, if you find one foraging on ivy.

It seems to be getting quite well established in southern England and is spreading inland in places, but records in the RX area would be useful.  We know it occurs in Hastings and at Pett but is it elsewhere?  For more information on this insect, including details of where to send any records if you have seen one (ideally sending a photographic record of the insect) click here

Both the English and scientific names of Dewick’s Plusia (Macdunnoughia confusa) are quite bizarre, and it’s a pretty moth too, related to the familiar Silver Y but smaller and brighter with a gleaming silver mark on the wing. First found in the UK by A.J. Dewick at Bradwell-on-Sea, Essex, in October 1951, it remained a rare vagrant until the last decade. Now it’s thought to be well established with at least four colonies in Sussex alone. Chris caught one at Rye Harbour on 2nd October, the fifth reserve record, but the one in my trap this morning was my first ever.

On the floor of my moth trap in Rye this morning was this uninvited guest, which according to Chinery’s Insects guide appears to be a male Dark Bush-cricket (Pholidoptera griseoaptera), a widespread species of rough verges, clearings and garden shrubberies that can be found as late as November. I’ve found crickets around the trap before but can’t recall finding one right inside!
