We had another successful Sunday with the Young Naturalists group recently, looking at three very different aspects of the wildlife at Blashford Lakes. First we unpacked the overnight light trap, which is mainly used to keep a record of the moths on site, but the first insect out of the trap wasn’t a moth at all, but a cockchafer beetle (or May Bug, if you prefer). These large and impressive beetles are only on the wing for a few weeks each Spring, and this one was sufficiently sleepy to allow us to pick it up, and feel it tickle the hand as it tried to cling on.

Thanks to Fletcher for the brilliant head‐on photo. Most impressive of the moths was a Poplar Hawk Moth, and this time Fletcher gave us a profile photo. We also managed to identify Light Emerald, Treble Bar, White Ermine, Scorched Wing, Clouded Border, Nut‐tree Tussock, May Highflyer, and a couple of what we think were Orange Footman.

The rest of the morning was spent searching for snakes. A team of Blashford volunteers has laid out a number of tin sheets and felt squares for snakes and other reptiles to use. They are tucked away well hidden around the reserve, and only checked once a fortnight to minimise the disturbance for any snakes which might use them as shelters and places to warm up. We had special permission to lift a few felts and look underneath, and we had also heard that a baby grass snake had been spotted underneath a log in the Badger Wood area, when a visiting school had been on a search for minibeasts. So we were delighted when we turned over a log, and there was a small grass snake curled up underneath. Again, Fletcher was quick enough to capture a photo before the snake wriggled away into cover.
The photo also shows the snake’s nictitating eye membrane, a translucent protective cover over its eye. We found another four grass snakes under another of the felts, all of which looked to be youngsters, but they didn’t hang around long enough for a photo.

After lunch we headed over to the north side of the reserve, to have a look at places where adders have been seen basking in sunny spots in the undergrowth. We didn’t see any adders, but while we were out we took a look at the tern rafts which have been moored in the lakes to attract breeding Common Terns. The terns don’t seem to be in charge of the rafts on Ibsley Water, where the Black‐headed Gulls have taken over, but back on Ivy Lake we counted between 8 and 10 terns which appeared to be sitting on nests on the rafts. We also checked the rafts out on Ellingham Pound, where again the Black‐headed Gulls were in charge. While we were looking at them, Geoff spotted a Hobby, hawking above the trees, and we watched as it appeared to eat a dragonfly on the wing.
This month the Young Naturalists are meeting on Sunday, 26th June, when we will be joined by Claire Sheppard, a local photographer, and we will be getting tips on improving our wildlife photography. For more details, see:
