Hello Bug Man!
We love your site in this house! While at the shore each year I enjoy photographing butterflies. I am attaching several photos of two butterflies that appeared to be wrestling on the ground. This went on for a few minutes with the two ultimately flying off in different directions. I have never seen such aggressive behavior. Is it associated with mating? Any help appreciated. Thank you in advance.
This is a pair of Monarch Butterflies. A mating pair will stay engaged for a lengthy period of time. Perhaps what you witnessed was a difficult “uncoupling”.
