My name is Dr Margriet Dogterom and am the founder and owner of Beediverse. I write this blog for all who love bees and who want to learn more about these wonderful creatures.
This photo shows two nesting tunnels (half of two nesting tunnels) containing two cocoons inside their mud cavities.
When nesting trays are not completely snapped togethr, a gap is present and lets air into the nesting tunnel. Consequently the mason bees muds over the gap forming a super – wall.

Subject: weird yellow fluffy substance found
When I was recently taking down my mason bee hotels and houses, I found a yellow fluffy substance in several of the boxes. It seems almost like wall insulation. One seemed to have cocoons in it.
Do you know what this is? Should I just clean the cacoons and boxes as usual with Chlorox? Do I just throw this stuff away? leave it in the recycle?
An interesting observation from Diane.
“This morning I peaked into small observation nest purchased some years ago
and noted a bright red color on top surface of one edge of two
cells…do you know what this might be?
Ohh how lovely. The bee has collected pollen from two sources, one flower
with yellow pollen and the other flower with orange pollen.
By touching the anthers of flowers you can see there is quite a lot of
pollen colors out there. One flower that has bright orange pollen is theTiger lily.
|This is a picture of a 3 nesting tunnel observation/viewing nest. The lowest tunnel is empty. The middle tunnel contains 3 completed chambers with pale yellow pollen. Two cells ( of the four) in the upper channel have bright orange and yellow pollen as part of the pollen lump. There is even a bee in the upper nesting tunnel.|
|Here is a picture of the same nest taken about a month later.
Cocoons are fully formed with adult bees inside.
Here is Frank’s third photo.
These grubs, may well be the ‘fruit fly’ Joe S. took and I wrote about on Jan 7th 2011 in this blog. Joe mentioned these fruit flies had red eyes. A friend of Joe’s searched the web and came up with “houdini fly” Cacoxenup-inbagator flies.
If you still have these grubs, set them up in a moist warm environment such as a petri dish and see what comes out. What an interesting project for a child who is interested in science. The search continues.
