?Mighty Mites

I've just been sent a photo for identification from a member of the Harrogate & District Naturalists' Society which shows some phoretic mites on a woodlouse in his garden. At first I thought it was just "ordinary" phoresy until I found this information which has horrified me.

Who are these people and is what they are doing legal? To put it mildly the consequences could be disastrous!

Re: ?Mighty Mites

The good news is it's out of stock.

These are presumably native species (otherwise they'd need DEFRA approval which I think would only be granted after extensive trials?), so probably most of what they claim is guff, based on speculation. Nature just doesn't work like this!

That's my amateur's opinion....

Re: ?Mighty Mites

The mighty mite looks like one of the predatory gamasids that are abundant in all compost heaps. Adding 500 to a population of 20,000 seems a bit pointless, possibly even a waste of money. And if they do manage to kill off all the springtails, woodlice, nematodes and fly larvae, there's not going to be much left to do the composting. Hair restorer, anyone?
