Varroa

So was at the hives again today, to do a full inspection. Before that I thought I'd take a look at the varroa boards. At first I saw nothing. And I thought, Great, no varroa! But I didn't really believe that and I started looking more closely. Then I saw the first one, the another. In a few moments I was seeing nothing but varroa mites and I realised I had gone to the other extreme. So I looked again, trying to count only what I thought with high probability was a varroa mite. The drop in each hive was about 10 for two days, which is ok.

In the photo below the thing at the bottom right is definitely a mite, as you can see its horrible crab-like legs. The other probably is one too, possibly with legs tucked in or chopped off.
I make no apologies for the size of the photo - that way it's easier to see the blighters.

Those might be mites

Have realised that drawing squares on the board will help enormously to count the mites, so that's a job for winter.

After I returned home I read that I should have left the boards in for a week. Will do so next time. But it seems that the hives are not full of varroa.

This is what the mite looks like - enlarged.
