Great Diving Beetles:

Hi,

I have been sampling ponds in Cheshire for beetles and bugs. I have come across Hydaticus seminiger frequently - a scarce beetle, but wonder if anyone out there has found any of the more uncommon Dytiscus species e.g. D.semisulcatus, D.circumflexus, etc..

By the way - the water spiders in Delamere forest are terrific - we don't see these very often in Lancs.

Cheers.

Hi,

Yes, Hydaticus seminiger, though a Nationally Notable B is widespread across the county in weedy ponds. We have four great diving beetles, Dytiscus marginalis, D.semisulcatus, D.circumflexus and D.circumcinctus in a scale of rarity.

This was in my moth trap this morning in Poynton. Not sure which one, but maybe of interest to you.
