I think this is Racomitrun lanuginosum when it is wet. In striking contrast to when dry.

Although both conditions are striking.

Leaf Cutter Sp Megachile Sp (to be confirmed)

Pale hairs on clypeus and thorax with some black hairs on top of the head. There appears to be a little tuft of orange hair visible from the scope. Somewhat festooned with mites?

M centuncularis perhaps?

Not quite

The Wonderful Mr Willughby's Bee

Willughby's Leafcutter Bee (Megachile willughbiella)

Thanks to Nick Owens for id.

Nick then passed on these comments, which I ma very grateful for.


M. centuncularis has only orange pollen hairs under its abdomen – and they stick out round the edge like a halo, when seen from above.
M. willughbiella and M. maritima both have dark pollen hairs near the tip, but maritima has whitish hairs towards the front end,
whereas these hairs have more orange colour in willughbiella (photo p. 148 in Bees of Norfolk).
You can’t really see this in your photo though.
M. maritima has more prominent white bands and also longer hairs on the front basi-tarsi if you can see that!
I think they are short on your specimen and the bands are not obvious.
You can see these hairs on the Holkham photo against the yellow petal. M. maritima is darker on top when fresh.
Hope that helps – always tricky with photos. A profile photo is useful for Megachile.
I’ve added M.circumcincta in case you see it (present at Holkham on bird’s-foot trefoil).
It has long hairs on the top of the abdomen which are black towards the hind end and no clear bands.
