Q.Is this a Oleander Moth?
I found these caterpillars just eating away on my mandevilla today. There are no Oleander’s close by but are several more mandevilla’s. Should I worry about it spreading to other plants. What is the best way to rid the plant of these caterpillars?
This is the caterpillar of the Gulf Fritillary.
It’s brilliant orange coloring makes it easy to spot and you can often see the silver spots of the underwing when it’s at reast or feeding. The caterpillar is also orange and black with fearsome looking, but soft, spines.
