Hi Daniel,
Hope you like this sequence.
The male had to wait for less than a minute with his robberfly for a female to arrive. When she did, he started to make what we would call beckoning motions, by repeatedly curling and uncurling one rear claw. All the time he slowly moved his abdomen into position for mating. When he locked with her she immediately let go of the grass and started to thrash around, at which time he passed her the fly and she settled in to dine while he went about his business. After mating her grabbed the fly back and took off, probably to use it for his next conquest, the cad.

Hi Trevor,
This series is phenomenal, and your firsthand observations are priceless.

We wonder if there are other observational accounts of the male absconding with his nuptial gift after getting his way.

  1. I am involved in writing an Animal Behavior textbook that will be published by Oxford University Press USA. I am seeking permission to reprint your three images of a hangingfly transferring a nuptial gift to a female.
    Thanks in advance for your help.
