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

Hi

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?

Hoplitis claviventris - adding wood dust to her nest plug in bee hotel

I put bee hotels up in my garden for the first time in spring 2014 & had an enthusiastic response from a number of small bees Ian Beavis kindly identified as Hoplitis claviventris. I was photographing one of the females as she was sealing her nest, and followed her as darted in and out of adjacent empty tubes collecting what I think was wood dust and placing it in the middle of her masticated leaf seal.
