Raising Common Buckeyes
The hardest part about raising Common Buckeyes is finding the caterpillars. Especially if you have a yard full of ribgrass plantains.
I recommend growing ribgrass in one gallon pots and place them in an open location where the female has access to lay eggs. This way you can easily monitor the plants for caterpillars. You can transfer the found caterpillars to a critter keeper for hand raising.
Also grow some ribgrass plants in small containers that will fit inside a critter keeper. When caterpillars are ready to pupate they will usually climb up to the cage lid to make their chrysalis.
Butterflies that eclose in September and October will be the rosa form (also called fall/winter form). The ventral hind and forewings will have variation in reddish color and markings.
Additional host plants include: toadflax, snapdragons, Ruellia, Verbena, and turkey tangle frogfruit.
