This is my first bee hive. I purchased a nuc 4 months ago where I transferred the bees into my flow hive brood box. It is July 21st and I live in west Texas where it has been hot - in the 90’s during day and 65 degrees at night. I currently have one brood box. It is 8 frames which were all naturally drawn out before I added the one flow super box to it. The flow frames are currently about 60% full of nectar and probably 10% capped honey. They have a tarp over them for some extra shade and have plenty of water. The hive is not aggressive and appears to be doing good other than the dead bees on the ground. I did not see much pollen coming in so I am thinking this might be dearth. Would someone be able to tell me if this picture of dead bees, I believe are drone bees, is due to dearth or another cause? I found several dead ones along with a few others that were barely alive. If this is dearth, do I just give them pollen patties on top of the brood box or do I need to supplement sugar water as well?
Thank you for your help,
