Here's something you don't see every day (unless you're looking for them). An undescribed species of springtail that seems to have invaded the UK. There appears to be a few different species, all unknown elsewhere, but presumed to have come originally from Australia. This one seems to get to a maximum of 0.8 mm long, but I'm finding them by beating foliage and low vegetation all over the area.

What an amazing post along with your regional summary here It's a shame that Naturalists don't respond to these types of post.

I cannot separate this 'springtail' from the lookalikes here but would like to be an agreer - can you help ME a little more?

I like to think that they get read anyway...

At least, I hope so - there's so much posted on iSpot that things do inevitably get missed.

For this one, there's been a lot of discussion on places like Flickr regarding the new katiannids, and this guy has loads of them:
The patterns are broadly similar in the group, and do vary within a species through their growth, but the colouriing of this one seems to be pretty distinct. They're surprisingly widely known in the UK now - Cornwall, Shropshire, Nottinghamshire, Surrey... I've been trying to find what else I was reading at the time, but no luck yet.
