I'm basically a birder but I do take an interest in what else I see around.
Yesterday I was on a pathway following a small river and saw what I believe is a Wasp nest. I say 'believe' because the insects concerned were much small and darker than Common Wasps (to which I am allergic by the way so avoid if possible).
The first shot shows the immediate location of the nest and you'll see that it's in a steep bank. The bank is about 10-15 feet high and was probably cut away when the path was constructed; it has trees on the top and is well covered with plants, including the brambles that you can see. Along the bank are several erosion gullies, usually close to tree roots, and the nest is in one of those, which raises the question as to how they managed to build it. The nest is central, just above the foliage sprig.
My first thought was that they might be Digger Wasps and had burrowed into the bank and built inside during the dry spell that we had a few weeks back, since when the rain had washed away the soil covering and exposed the nest. You can see the normal type of erosion debris at the bottom of the shot. The alternative would be that they simply built into an existing gully but then why didn't they get washed away when the rains came and in any case, why doesn't the nest fill up the water (the lower part anyway)?
Shot 2 shows the nest, and 3 shows quite a lot of inhabitants crawling around on the surface (repairs?); note the entrance on the LH side (as you look).
The insects were very busy, with a constant stream in and out but I couldn't find where they were going (probably across the river to a large garden) so couldn't get an individual close-up
So, can anyone please tell me what species of Wasp (if they are Wasps), and please note in shot 3 the odd man out on the right, what is that?
Thanks in anticipation,
