The family Lycidae are the net-winged beetles. They are unusual in that the adults form aggregations aka “swarms” in some circumstances. These are occasionally found on rotten wood of common species of temperate hardwood trees. The larvae feed under the bark, consuming the wood. The adults (5-8mm), which are toxic to predators, may visit nearby flowers to feed on nectar; others do not feed.

I found these at the end of a mushroom foray. We were just walking back to our cars when I spotted these orange insects walking around on a prostrate, rotten, deciduous tree log on the ground beside the road. My initial assumption was that they were true bugs (Heteroptera). However, I soon realised that they were beetles and something unusual. (I have been looking at rotten logs for fungi and other wildlife for decades and never seen this before). I could see up to five of them at a time.
I had some problem with my flash guns, details of which I cannot remember, such that about half the images were lost. Those which survive show what a range of poses these beetles can provide.
These beetles seemed to be searching for something…

Perhaps it's way over there?
Could it be up above me?
I'll just check behind
Did it drop over the cliff?
It's not in the gulley

Thanks. I was lucky with the OOF background in that one. On this occasion, I did change the sequence for that of shooting.

This species had not previously been recorded at the nature reserve so I have provided their Ecology Officer with the details and offered the use of images.

Thanks, but not really. There are only a few beetles of that colour scheme in the UK. I thought they were Cardinal Beetles but their size and the pattern of red or black colours on the thorax led me to look a bit further. Once I found a family of beetles with the behaviour and appearance it was a choice between two species, one with yellow tips on its antennae.
A lifetime of identifying insects, not usually from photographs, does help!
