What Do Fritillary Caterpillars Eat?

Fritillary Butterfly are those Brushfoot butterflies that come in oranges, browns and black. Most of us know and love Gulf frits, Great Spangled frits, Variegates frits, Aphrodite frits, Silver bordered frits, Meadow frits and Regal frits, if you’re east of the Mississippi River.

Now that I’m relocated to Georgia, the fritillary butterflies here mostly deposit their eggs on Passionflower vines, easy to grow Southern garden favorites. Passionflower also attracts other butterflies, including Zebra heliconians.

The most common hostplant for Fritillary butterflies comes as something of a surprise, and are in most gardens. Fritillary butterflies mostly lay their eggs on violets. it still seems incongruous, that their caterpillar hatch on and feed upon these tiny little plants, present in the early Spring, and not so much as 4″ above the soil.

Shown here are Downy Yellow Violets, that I spotted in Raccoon Creek State Park, in southwestern Pennsylvania.

Holli and Leslie would surely have me remind you, urge you, to please delay your annual leaf raking of your lawns, until mid-Spring. Why? Because Fritillary caterpillars spend the winter as chrysalises each with a rolled leaf around them, right there in the leaf drop sitting on your lawn. Rake your lawns in October/November, and you may be removing (killing) dozens of Fritillary cats, they, awaiting the onset of Spring weather.

    • Yes, Yes. Yep, a missed a stormy northeastern winter this 2018/2019. Petra has a huge yard, many squirrels to chase, and she just loves Georgia. The butterflies here fly from March to November, a real treat for kiddo here.
