Hi,
I just unwrapped a straw from this summer and in it I found 4 compartments separated with Sticky reddish Brown resin. In each compartment attached to the resin plug was a glob of soft yellowish material with a white larva which seemed to be attached to the glob on both ends. 
These were in a straw suited for summer bees. The larva varied in size from about 1/8th to ¼ inch long.
Would you have any idea what these might be? This is a photo of the resin and the larva. Thanks Norman Z.
Thank you for the pictures Norm. I do not know what this is. It looks like the resin is anchored in the resin. If you can, keep it in a petri dish with some moisture and see what emerges. Margriet
