Emptying the moth trap this morning revealed a beautiful garden tiger moth, which was definitely a treat to see. When disturbed they display their orange hind wings with blue-black spots, the bright colours acting as a reminder to predators that they are unpalatable.

The larvae of the garden tiger moth are large, black and covered in long, dense, black and ginger hairs, giving them their name the ‘woolly bear’. They feed on stinging nettles, dock leaves and a variety of garden plants. They can be seen from August until the following June and are often seen moving rapidly across bare ground when fully grown so are a good caterpillar to keep an eye out for, although it is best to leave them to it if you do see one as the hairs can irritate.
When the sun is shining the pond is still a brilliant to spot to look for dragonflies, with common darters often resting up on a chosen spot and both brown hawkers and emperor dragonflies hawking overhead or egg laying:

There are still plenty of damselflies around and I managed to photograph this pair of common blue damselflies mating. The male is blue and the female is a more camouflaged olive green colour:

The male dragonflies and damselflies have two pairs of hooks at the tip of the abdomen which they use to grasp either the neck (in damselflies) or head (in dragonflies) of the female. Pairs can often be seen flying together in tandem and shortly after capturing a female they will mate and form the ‘wheel position’ seen in the image above. Some species remain coupled for several hours amongst vegetation whilst others, like the chaser dragonflies, couple briefly for just a few seconds. Following mating the female is ready to lay eggs.
There are also still plenty of butterflies on the wing, including this common blue which was outside the front of the centre earlier today.
On Sunday we held another of our online Young Naturalist catch ups where we expanded on the last session delivered by Owain from Amphibian and Reptile Conservation and discussed all six native reptiles. We were treated to some fantastic photos by Kimberley, taken on her phone, of a very friendly male sand lizard she had encountered whilst walking her dog at Dewlands Common in Verwood.
I used to visit Dewlands Common regularly when employed by East Dorset District Council so it is great to know they are still present on the site.
Will also shared some photos he had taken, including a lovely photo of a wool carder bee on lamb’s ear (Stachys byzantina). We had been hoping the lamb’s ear in one of the planters outside the Education Centre would attract wool carder bees as they will scrape hairs from the leaves to line and seal the brood cells in their nests, but sadly there has been no sign of any.
Will also shared a photo of a small skipper butterfly which was taken up on the Laverstock Downs, a gatekeeper which he had photographed at Horatio’s Garden at Salisbury Hospital, and an abandoned robin’s nest in his bird box at home – the robin’s had for some reason moved elsewhere.
We also looked at the moths in the light trap, where the highlight was this very fresh looking Sallow kitten:
Finally regular visitor and volunteer Phil shared this photo with us of the Osprey which visited on the 16th July. It was only here on that day, but did spend quite some time sat on the perch out on Ibsley Water and Phil was able to get a photo from a distance. I was on leave that week so completely missed it!
