So this is interesting. Several weeks ago I saw a bumle land on a leaf and it was watching the girls fly out of the hive. All at once it took off like a shot and caught one of my bees in mid flight as it exited the hive! Now I have watched my bees and small bumbles working the same flowers with no problems. Today I watched another bumble grab a be in flight and land on this leaf. These are not eh regualr bumbles, these are at leaste 3\4 " long. A BIG bumble. I do not know much about bumbles but the queens are big and they do fly around. Has anyone seen this behavior? I found it interesting. Thanks.
