A day off in the heat, I spent much of it in the garden, although staying largely to the shadier areas. I was going to have a look for insects, in the hope of adding new species to my garden list, but my willingness to stay out in the full sun for very long thwarted this. I did manage to record one new species though. I used the pheromone lures for clearwing moths again and this time attracted several male red-tipped clearwing moths, these are quite frequent at Blashford, but I had not recorded them at home previously. I did try to get some pictures but in the heat they were so active that this proved impossible.
The mini-meadow is looking great now, the ox-eye daisy and corky-fruited water-dropwort are just starting to go to seed but the field scabious, knapweed, wild carrot and bird’s-foot trefoil are just coming to their best.
Both the scabious and knapweed are particularly good nectar sources, being very well visited by bees and butterflies.
The smaller individual flowers that make up flowerheads of wild carrot and corky-fruited water-dropwort are less attractive to larger insects but will still have lots of insects, in this case pollen beetles.
A warm clam night, ideal for moths and so it proved, with the best catches of the year so far. There was not a lot of great note, just all the usual suspects plus a lot of small species, which tend to be caught much more on calm nights. In fact it was the micro moths that provided the best moth of the night, assuming I have managed to identify it accurately, it was a Tortrix moth, Pammene trauniana.
The grass snakes were putting on a show again yesterday at Ivy South Hide, with four individuals on the tree stump in front of the hide.
Signs of the year moving on are starting to appear, a common sandpiper on Ibsley Water will be one on the return journey south and the moulting goose flocks are building in size.
There was clearly an arrival of painted lady butterflies with several around in the afternoon, perhaps more to follow and maybe other species too.
Following yesterday’s clearwing success, I tried the lures again at lunchtime and again attracted a single orange-tailed clearwing. This time I did manage some rather better pictures.
They say “You should always expect the unexpected” and it seems I should. Today, at lunchtime I decided to deploy the pheromone lures for clearwing moths, these are artificial chemicals that mimic those released by female moths to attract the males. They have been synthesised for most of the clearwing moths, a strange group of day-flying moths that look like wasps and are usually very rarely seen. The use of pheromone lures has made finding them somewhat easier, but they are still not that readily seen.
At Blashford we could have several species of these moths, but I have only ever seen and attracted to a lure, the red-tipped clearwing. Today I tried four lures for a range of species including yellow-legged clearwing, whose larvae feed on oak, of which we have lots. I sat back an ate lunch whilst keeping an eye on the lures. I expected to see something at the red-tipped lure, but there was no luck. Then at the yellow-legged lure there was a moth, hovering continuously around the lure, I grabbed the camera and got the best flight shots I could at 1/1000th of a second.
However this was not the expected yellow-legged clearwing, but the other species that can come to the same lure, the orange-tipped clearwing, in Hampshire a moth of the chalk downs where the larvae feed on wayfaring-tree. Blashford is not on the downs and does not have wayfaring-tree, however we do have a few guelder-rose a less frequently used food-plant and I assume this must be what they are feeding on.
