BWARS forum - first, please read this

This forum is a place to discuss matters related to BWARS and general matters related to aculeates.


It is not intended as a forum for identification queries. We may add this feature in due course, but meanwhile, if you need help identifying bees, wasps and ants, please use either iSpot or the BWARS forum on Yahoo.


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.

Weighing Bees


I am a student at the Open University doing a degree in Environmental Science. I am about to undertake a project/investigation into pollinating insects. As part of the investigation I will be recording the weights of Bumblebees which (as far as I can gather) range between 0.05g and 0.90g.

Does anyone have experience of recording the weights of insects and if so can anyone recommend a budget set of scales that give sufficient precision/accuracy for this purpose?

Bombus monticola records - lancs

Three Bombus monticola females spotted at White Coppice, Lancashire (south of Brinscall) on sallows 11.30 - 13.00, 10/04/15 - two large, lively and obvious queens, one female more worker sized and fairly inactive.

Excreting pollen

I was watching an Andrena sp. that apparently started to excrete pollen on a leaf. Can anyone tell me what was happening please - thanks.

Anthophora plumipes

Good morning.

Several of my client have these coming down the chimney. What is their lifecycle?

Thanks in advance.
