Travel Notes

As we travel widely during the summer looking for insects to photograph, Roger Edmondson and I have decided to put a record of our more interesting finds on this website. New entries are not always entered in date order so please check for changes by clicking on 'What's new' on  the home page.

In early May this year Roger and I were trapping on the coastal sand dunes at Berrow in Somerset. It was another of those cool, clear evenings after a warm day and there were not many moths arriving at the lights, so we decided to search for larvae to pass the time. 

Two of the larvae we found on Grey Willow Salix cinerea had a dark length ways stripe and were about 15mm in length. I later identified them at home as the larvae of July Highflyer Hydriomena furcata. Within a few days one of them had pupated and the other only grew a further millimetre or so in size before pupating.

In less then a month one of them has emerged and I was surprised to find it was a colour form that I had never seen before. I have photographed forms with a cream band across the wings, but never with such a broad band as this one.

The larvae also feed on other Salix spp, Hazel, Heather and Bilberry. All of the moths above had a forewing length of 15 or 16mm, but they are sometimes as small as 13mm. 

This species is common throughout Britain and Ireland and is a regular visitor at light traps. The usual flight period is between mid-June and mid-August in southern Britain. They start a month later in Scotland occasionally through to early October.

One of the aspects of studying moths that makes them interesting no matter how long you have been doing it, is the discovery of a form of a species that you have not come across before. This was the case for me with the olive banded form of Pine Beauty Panolis flammea that came to a UV light in my garden. Although I have never lived in an area where there are lots of conifers and the moth is common, I have seen a large number of them over the years, but never this form.

The form is not rare and perhaps i have missed it when I have had faded or damaged specimens arrive at the trap, but I definitely have not had it in the garden before.

For comparison, a strongly coloured specimen of the red form is shown below.

The larvae of this moth feed on the young needles of pines, including the native Scots Pine. They can be a pest in forestry areas, as they were when Lodgepole Pine was commonly planted in northern Scotland in the 1970s.

The moth is found throughout most of Britain and coastal counties of Ireland, apart from central northern England and parts of western and northern Scotland, and parts of the Hebrides.

Both of the moths in the pictures had a forewing length of 15mm.
