Sapyga quinquepunctata and forgetmenots, Osmia and hollyhocks

I watched a female Sapyga quinquepunctata enter holes where I had recently observed much activity of males and females of Osmia caerulescens, and Osmia laeiana. I had read that this wasp only visits thyme, but when it left the hole, it ignored the nearby thyme and refuelled on the abundant forgetmenots. Meanwhile, the females of both Osmia species have begun their annual pulp making work on the hollyhock leaves. What looks like slug damage is due to bees - see photos. I haven't seen these bees visit any other plant for pulp.

Source leaves for Osmia

That's interesting Martin. I've had O. leaiana and O. caerulescens nesting in the garden but have never found the source for their chewed leaves. I'll keep an eye on the hollyhocks!

Osmia caerulescens / hollyhocks /

Fascinating post, thank you. I have hollyhocks directly below where the Osmia caerulescens are nesting, so will check them at dawn! Also a Sapya q. so will try and confirm if she is foraging on forget me nots here too.

S. quinquepunctata on Saxifrage

A female Sapyga quinquepunctata has been nectaring on saxifrage flowers in our garden today.

Sapgya flower choice and Osmia hole

Very nice photo.
Here is a rubbish pic of her on mayweed (Anthemis sp) and a couple of badly lit photos (my flash is broken) of the same female Sapyga checking and entering an Osmia hole. She goes in head first at first, then a few seconds later, comes out again and then reverses in - presumably to lay an egg

Osmia and hollyhocks

In our garden they go for a small herbaceous potentilla and nibble fairly neatly round the edges of the leaves.

I shall have to keep an eye on the hollyhocks from now on!
