Syrphus's picture

I am going against an

I am going against an impressive list of supporters here, but I will stick my neck out on this one.

There is no evidence of the yellow thoracic hairs expected on vespillo, which is also a very scarce species in Scotland. We can't see the shape of the hind tibia, so I think I would want a reason to call this vespillo rather than investigator.

N. vespillo is not mapped on NBNG for the W Isles, nor is it included in Waterston's faunal list. To make this the first record for the Isles needs justification.

I shall show my ignorance

I shall show my ignorance here- Hind tibia? Like back leg? Will look out for it again tonight and just in case- exactly what pics of what do you want? Yellow hairs? there appears to be hair of some sort in the pic posted- not what you need?

OK - sometimes you need to

OK - sometimes you need to get technical!

The hind tibia is the second long part of the back leg. You can see it in the picture, the last bit before the segments get smaller, with a spine on the end. In vespillo that is distinctly curved if you see it from behind, and straight in investigator.

The hairs that are crucial are long yellow hairs on the large black plate just behind the head and before the orange bands. N. vespillo has them, investigator does not. It is the lack of hair, plus what we know (or think we know) about the distribution that makes me pretty sure it will be investigator.

If you can get another pic showing the back leg, that might clinch it (hairs can be rubbed off). You can add the pic to this post rather than post separately.

Looks right for N.

Looks right for N. investigator to me as well - not nearly hairy enough for vespillo
