A "who done it" mystery in Native Plant Gardening
It was a blissful summer day. Monarchs floating thru the air. A black and gold bumble be (Bombus auricomus) and a flying shrimp (Hemaris thysbe or Hummingbird clearwing moth as some call them) were peacefully sharing a thistle flower head. The shrimp then moves on to a lower flower head on the thistle. When all of a sudden, from upper left, another smaller flying insect appears. With incredible speed, the mystery insect makes a beeline (😜) for the shrimp and KO's the unsuspecting nectar-enjoyer, sending it head over shrimp-tail backwards off the flower. It then somehow ricochets off the shrimp and back up to harass its bumble bee friend.
How in the immutable laws of physics was this possible? Who was the tiny attacking insect and was there a 2nd attacker hiding in grassy knoll?
Here is a recreation of the events performed by live actors to help clarify the facts of the case: https://www.youtube.com/watch?v=tBz3PqA2Fmc
Seriously, I often see something that seems like a smallish bee or fly zipping all around harassing larger pollinators (like swallowtails, large bumble bees and clearwing moths) to the point of temporarily driving them off the flower. In the slowed down video it looks like a small type of bumble bee. Anyone know of one that does not like to share?
