Naturelog: 28th July

At present both the Big Butterfly count and the national Dragonfly survey are both running and so I decided to combine counts for these with my weekly counts on the local patch. It was a warm but quite windy day and so conditions were not ideal and this was reflected in the low butterfly count – just a Small White and a Speckled Wood seen. However there is always something to find and today it was two new records for me – the first of these was a female Tufted Duck and 4 young. Although the Tufted Duck are present all year round on the Tarn, this is the first time I have seen evidence of successful breeding. The youngsters are quite large now and look very healthy so hopefully, they will make it to adulthood.

The second new record was 2 Jersey Tiger Moths. This bright, colourful day flying Moth is a relative newcomer to London. In a 1903 survey, it was found only in one location in Devon and in the Channel Islands, but in recent years it has spread throughout southern England and arrived in 2004 in London where it is now regularly recorded.

After completing the weekly survey I went onto Eltham Palace to check out the moat for Dragonflies and was pleased to find a number of Small Red-Eyed Damselflies plus a single Migrant Hawker
