Can anyone help with this one? It has a very distintive yellow underside to its abdomen. I thought it would be easy to find, I guess I can't see for looking! I need to get a better book.
Yep, I'd go Osmia rufa on that too - note how faded and non-rufous she is. They are almost over now and will soon be replaced by Osmia coerulescens, the Blue Mason bee.
Right or wrong it's having a go that counts; we all make and learn from our mistakes and misidentifications, but it's the fabulous discussions that it all promotes that we are looking to encourage.
Keep up the good work folks!
Thank you both. Now I know where to look and have seen other pictures it looks right.
I agree, the only way to learn is to have a go, but it is nice to have a helpful environment like this were others will help rather than abuse.
