Bizarre!
I have a swarm that I hived using a medium super on 10 frames of foundation. I didn't have any deeps when this swarm took off on April 14. Once the colony built out the medium, I added a deep with 10 frames of foundation and continued to feed 1:1 syrup. They haven't really been overly enthusiastic about building out that deep but the activity from the hive was acceptable.
On Sunday when I removed the insert from my screened bottom board, I noticed several 1/4" worms and 2-3 worms that were about a inch long. Based upon what I have read on this forum, I thought that I had a weak colony with too much space to defend and had wax moths. So, I readied my equipment to reduce the colony to just the bottom medium and, if necessary, put a divider board in this box if they were not defending all 10 frames.
Yesterday, when I opened the hive up, they had drawn out about 4 frames in the deep that was on top of the medium and it was clean............no signs of moths at all! After I removed the deep, I inspected the brood medium on the bottom and found it to be clean as well. The bottom board screen was absolutely clean as well. I only saw on SHB and killed it.
Sooooooooooo.........I don't know what was living on that bottom board insert. I can only speculate that the larvae/worms may have been SHB larvae or wax moth larvae that the bees couldn't kill because they were separated from the board insert by the screened bottom.
Thoughts?
