Two interesting micro moth records from Flitwick Moor 28th June 2014

The Wildlife Trust for Beds,Cambs & Northants & The BNHS held their annual Invertebrates Day at Flitwick Moor on 28th June 2014. All was fine until it started raining just after midday which did not stop until after 3pm. As it started raining I was collecting leaf-mines from a Crab Apple in the meadow and found an interesting large Coleophoriid case that I did not recognise. On getting home I identified it as Coleophora siccifolia, a scarce species with five previous Bedfordshire records. Two of these were adults at Turvey Abbey in 2001 & The Cockayne Hatley Rothamsted trap in 2005.There are three previous larval records, two of feeding signs in N Beds in 1992 and 2005 and one larval case in 1992 in Sharnbrook. This then is the first record in 9 years and the first in the centre of the county.
The second find was whilst wandering round in the rain in the afternoon collecting leafmines for id later. One I had been looking for on Honeysuckle and happily found was Perittia obscurepunctella. The only previous record of this in the county was of an adult in a light trap at Apsley Guise in 1983.

Melissa took some nice photos of the Coleophora case and I scanned the Perittia mine, both ids have been confirmed by Beds Micro-moth Recorder David Manning.

Cranfield Uni bioblitz bonus

Andy and I ran two MV lights for a couple of hours at Cranfield Uni last night as part of their bioblitz weekend. Prospects weren't good as it had rained during the day and it hadn't been especially warm. We didn't catch large numbers of moths, or as many species as one might expect at this time of year. However, late on we found a single Double Dart, a moth species that hasn't been seen in the county for nearly 11 years and one which we thought we would never see in the county. So was a good end to the evening.

Of the 5 Black Hairstreaks I saw in Marston Thrift today this one obligingly came down for a brief photoshoot.

A rather gruesome surprise

This year I have been making a concerted effort to record more lepidoptera larvae, and in particular moth larvae. To that end I have been visiting various sites with a beating tray to collect caterpillars off a selection of trees and shrubs. So far Andy and myself have managed to find nearly 50 species and I will post photos of some of the more interesting finds later in the year.

On Sunday I beat a Grey Shoulder-knot caterpillar off oak at MVCP during a BNHS meeting. I took it home as I didn't know what it was. On Sunday evening it was fine and I photographed it.

I checked it on Monday and it was still looking ok but it hadn't eaten much. On Tuesday evening I checked it again and got a bit of a shock.

It was no longer moving and appeared to be stuck to the leaf with several cocoons attached to it. I've seen parasitised larvae before where there have been a few cocoons but nothing quite to this extent.

Satin Lutestring new to Beds

A single Satin Lutestring came to MV light at Flitwick Moor last night (6th), which is a an addition to the county list. The moth was caught during a Beds Moth Group meeting at the site, which was a last-minute change of venue as we couldn't trap in Chicksands Wood, as advertised. Unfortunately, only myself and Andy got to see it as the others who had joined us for the evening had left by that point - in fairness it was found around 1am!

There is an unverified record of the species from 1934 noted in The Butterflies and Moths of Bedfordshire (1997). No specimen was seen and the date of early May was really too early to have been this, so it had not been accpeted.

Lunar Yellow Underwing - a surprise moth in Bedfordshire

An excellent find by Robin & Fiona Wynde on Friday morning in their Potton moth trap was this Lunar Yellow Underwing, Noctua orbona. There have been reports of this in the county in the past but none of the historic records have a supporting voucher specimen so they are in doubt due to the confusion with other Yellow Underwing species. In the photos below the black sub-apical mark on the upper wing and the black crescent on the hindwing are the diagnostic features that separate this species from Large & Lesser Yellow Underwing.
