I was out on the eastern side of Ibsley Water with the volunteers this morning to clear the areas we cut and which are grazed by ponies of ragwort. It is toxic to animals, but they will usually not eat when it is growing, however they will if it is cut and gets mixed with grass or hay. At one time it was one of the commonest plants in this area but now it is much reduced and overall the grassland is looking much better, with quite a good range of species. A couple of highlights this morning were several patches of corky-fruited water-dropwort.
Corky-fruited water-dropwort is an Umbellifer, one of the carrot family and is very attractive to insects, this one had lots of pollen beetles on it. It is quiet frequent in unimproved grasslands in a swathe roughly south of the M4, so it is pleasing to see it at Blashford where the grassland is still recovering from the ravages of mineral extraction. Another find was knotted clover, a plant of dry sandy places, often near the coast, I am not sure if I have found it at Blashford previously.
At lunchtime I tried the pheromone lures for clearwing moths again, completely without success. However I did spot a handsome black-and-yellow longhorn beetle.
After doing various odd jobs in the afternoon I went to lock up the hides and found a pair of crab spiders on a hemlock water-dropwort flower head, The male is quite different from the female and a lot smaller so he has to tread carefully if he is not going to get eaten.
It seemed it was not only the spiders that were making plans, on a nearby ox-eye daisy I saw a female hoverfly Eristalis horticola, with a male hovering low over her and darting from side to side. I am not sure if she was impressed but he was trying hard to dazzle her with his advanced hovering skills.
I also found another slime mould, on the same log as the one the other day, although this was clearly a different species.
The only new bird sighting of note today was of a first summer little gull as I locked Tern hide. It was pleasing to see that the single oystercatcher chick from gull island has fledged and that the remaining one near Tern hide is close to doing so. In additions the single large lapwing chick is also close to flying and two of the smaller ones are still going strong. Even better was a sighting of two well grown little ringed plover chicks today. On Ivy Lake the common tern chicks are growing well and most broods seem to still be of three chicks.
What I particularly love about these blogs is that there are a couple of new things (lots today!) at a time, allowing me to learn a little each time. Ive never been good at mass learning. “Corky-fruited water dropwort”….where on earth do these names come from ;-). I MUST save for a decent macro camera 🙂
Really enjoy reading these updates! Remember being told once that Eristalis nemorum was the only one where the male hovered over the female like that – do the others sometimes do that too?
