American Snout (Libytheana carinenta)
June 14, 2007
I was photographing this American Snout when it moved to a different plant and I noticed it appeared to be laying an egg. After the adult butterfly moved on, I went back to the leaf and searched and found an egg.
Some butterfly species only lay a single egg at a time, others lay several eggs, while others lay dozens of eggs in a cluster. Some of the factors which contribute to laying large egg clusters are a relative scarcity of appropriate plants on which to lay eggs, opting for the benefits of gregarious caterpillars, or a lower population density which results in a butterfly needing to spend more time locating a mate.
