Point of clarification, please

I can't seem to find any reference to Cantharis livida form rufipes, let alone to C. rufipes. Could you possible post a reference, please.
What is the difference between this taxon and C. pellucidus?
Thanks.
Richard

I looked on Google and typed in Cantharis livida and found it on wikipedia. I am no expert on invertebrates so if you know what it is please feel free to correct mu identification

Cantharis livida f. rufipes versus C. pellucida

Hi,and thanks for replying to my query. I've checked out the Wikepedia page. I'm glad I now know of this form of C. livida. In Joy's 'A practical handbook of British Beetles' (which I've used for years but never noticed) I see it is allowed for in the final couplet. However there is an easy distinction: C. pellucida's head is black at the base but red near the front, whereas C.livida f. rufipes' has its head entirely orange/red. Also the apex of the hind femur is more broadly black in C. livida and very narrowly black in C. pellucida.
Looking at your photographs you can clearly see that on both characters yours is C. pellucida. This species is common, wheras C. livida, whilst not actually rare is x4 rarer than C. pellucida based on my records.
I'm glad that we've cleared that up: now all I need to do is find C.livida f. rufipes!

PS If you ever use Joy's key to Cantharis, beware there are a couple of mistakes in it. R.

Thanks

Thanks for the information and identification will use the Joy's key as I get quite a few were I live and will also now be looking for C.livida f.rufipes.I will also try and get measurements too as I presume this will also help.

Best wishes
