Hi Piersdy, Ive just noticed

Hi Piersdy,

Ive just noticed that the first ID you added here which included the common name 'Carrion Beetle' has aligned this observation with those of a completely different species- Creophillus maxillosus. I have removed my agreement from there (your binimial Necrophorus vespilloides was very close but should have been Nic).

Experts needed

It is incredibly frustrating to find these varied IDs (I realise there are only two here ♣), none with agreements.
Whilst I accept that separation of the Nicrophorus is difficult, there are a number of experts lurking in iSpot. Surely they should be on the lookout for such difficulties and offer comments at least.
Now see https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rj...

I am here TRYING to separate vesitigator from investigator for my post of the week!

♣ There's a good number of Necrophorus posts, some with as many as three IDs, few with experts' interaction. Just click on a few Other Obs. or search the site for Nicrophorus.
Name withheld! ha

Hi Derek, Its been 2 years.

Hi Derek,

Its been 2 years. I still think those black antennae are right for vespilloides- from what I know of these beetles. I'm not an expert but I think this is a reliable ID feature in this case.

As time goes on, there are so many iSpot obs. I reckon unless people are keen enough to trawl historic records, there are going to be many obs. un-engaged with such as this.

Im afraid I cant help with separating vestigator from investigator right now. Investigator appears to be a very abundant species, probably the most regularly posted on iSpot, of the black and orange sextons.

NicroSaurus

Yes, as you know, I trawl history, specially when I am researching a post for myself. That is what iSpot is for!
I have agreed to yours here because I believe you are right. Piers (Piersdy) was right too but he added the WRONG common name, so iSpot did as it was told (Creophilus maxillosus). I am not certain it would do that today.
Anyway I have done my research and feel a lot more comfortable - I saw my last Sexton beetle last century, mine is only the third for Orkney, the first since 2011. See my http://www.ispotnature.org/node/698223 NicroSaurus ◘! I am glad I have a decent camera.
