This was in a pheremone lure trap with a lure for Yellow-legged Clearwings.

The next two were in a pheremone lure trap with a lure for Cydia strobilella. I suspect that it's not the pheremonones that lure the beetles but they end up in the trap accidentally, rather like in a vane trap.

I forgot to record how I found this one but I was trying out my new vane trap at the time and I suspect it was in there.
