This weekend was mostly taken up with family time, but just managed to locate a few specimens in the little time I had.

A couple of beetles I am having trouble with:

This beetle flew in and landed on the back of my hand when I was working on the patio. c.4mm long - black with 2 dull red spots - very spiny legs - very distinctive was the two inner striations looping back on themselves. Did some browsing and thought it may be part of Histeridae family?

I realise that this is a click beetle, but I have no means of identifying it beyond that. Was 11mm long.


  1. Mark - there's a top Telferguide at to Elateridae. I struggled when trying it on a small one, but need to persevere more - and I did manage to confirm the Haemarrhoid Beetle

  2. Think the beetle is one of the Hydrophilidae - but if so, which one?? Soz.

  3. cheers guys, I shall check 'em out.

  4. Methinks I've seen your Ditropis pteridis in my own square (currently sinking under the weight of bracken...) and assumed it was a hopper nymph. Cheers for the heads-up.

  5. Been researching the beetle with the red patches and the best I can come up with is Margarinotus purpurascens, although the inner striae do not seem to match perfectly (but perhaps this is a variable feature). Can anyone confirm or reject this ID?

  6. Just tried out the click beetle key and came out with Athous haemorrhoidalis perhaps? [a musketeer with bum-grapes?]

  7. Mark, I'm sure that your click is the common Athous haemorrhoidalis. And the histerid looks right for M. purpurascens, comparing to my specimens.
