Found in pitfall trap in front garden next to cherry tree. Seemed quite agitated, looked like they were almost trying to fight each other. I wondered if they were rove beetle larvae as they seemed to flick abdomen when I got too close to them (I wouldnt know for sure though, Im very new to all of this). Found a few more a couple days later (sadly didnt think of taking another picture, silly me) and saw one about half the size of other. The ones pictured were around an inch long.
