Water bugs and beetles




These were found in the pond at Lorgba - which is only tiny, although quite deep - with its edge defined by a tractor tyre. The Water cricket (Velia caprai) is the handsome chap with orange sides. I am unsure what the water beetle is. Any suggestions? The beetle comes to the surface regularly to breathe by sticking its abdomen through the surface film and staying there for about five seconds - as can be seen in the photo - then zooming back down to the bottom.

  1. There are at least 30 different water beetles known from Islay, and that's not including the ones with long swimming legs - the water boatmen. There's a book in the Centre Library called 'A Key to the Adults of British Water Beetles' by C.E.Friday. You *might* be able to find it in there!

    There is only one records of a water cricket in our database (!) - but freshwater invertebrates are yet another neglected group!
