After I wrote last week’s post about insects gathering nectar and pollen from a flowering wolfberry plant, I visited the plant once more.
The adult butterflies were only sipping nectar from the wolfberry flowers and it is not a host for them. Snouts lay their eggs on hackberry trees (Celtis sp.)
The caterpillars that hatch from the eggs are green. Butterflies and Moths of North America website has some photographs of the caterpillars. When they are done feeding, they form chrysalids that are a similar green color.
Today, the wolfberry has finished flowering. I wonder where the snout butterflies are now.
