Beekeepers are on the lookout for bees with deformed wings in the hive. This bee has tiny, crumpled wings and would be unable to fly. This condition is transmitted by a virus, and is passed to bees by a parasite called the varroa mite, which attaches itself to bees and sucks its juices! If there is a heavy infestation of varroa mites then bees with deformities appear in large numbers in the hive. This is the only one I have found recently.
