SPIDER MITES

I love confusing myself. Insects are very confusing and so are rivets to some folk.
 I received an email from a lad who has built himself a hydraulic hot rivet squeezer. He said it's leaving a lot of squashed metal on the job and the plate edges are distorting. These are domed headed rivets, button heads to normal folk; so both tool heads are hemispheres less a bit. I was working from memory but rivet length is 1.5 rivet diameter plus the combined thickness of the metal to be joined and add a bit for pressure vessels. You also leave a minimum of two combined metal thicknesses from the edge of the plate being joined. Maybe one. Nay two sounds sensible. A pound to a penny there is an EU directive running to five hundred pages on it if anyone can be arsed to look. Pity they hadn't put their minds to building cladding, maybe they have but nobody could be arsed to look.

These insects are really small about a millimetre or two.

In the first picture you see a Harvestman carrying red spider mites, I believe it's symbiotic. In the second you see a red spider mite eating an insect. Fair enough but red two spot spiders, this has two spots if you enlarge the image, it also has a baby one joining in, are supposed to be veggi and yellow after their growing up three bits. There is a predatory red one, Phytoseiulus perssimillis. It doesn't look like this which I think is Tetranychus urticae. Why is it omnivorous? Why do folk have problems with riveting? The more insects I find the more muddled up I get.

I found a grand little beastie this week Its a lace hopper the image is rubbish because it hopped before I got another go.

A bit blurry but it is one and thank you Trevor at Three Counties for telling me. You could have told me the chances of finding another were zilch, spent a couple of hours in inclement weather trying to get a perfect shot. Never seen another. Bugger.
Have fun.
