I noticed this earlier on my arm, allowed it to crawl on to my finger so I could let it out the window and it bit me. The bite has swollen up a little but my partner has woken up with a 2cm lump from a bite, Might be coincidence or the same culprit. Anyone know what it is? Thanks
Strange that this animal actually bit you. It is the larva stage of a lacewing or goldeneye, family Chrysopidae. The larvae and the adults feed on aphids and are very welcome helpers to keep these pests under control.
