We’ve got silk moth caterpillars for sharing TODAY/Saturday from 10–6! 🐛
Choose from:
Luna moths (feeding on sweetgum)
Polyphemus moths ( oak)
Promethea moths (spicebush)
If you take some home, they’ll need to continue feeding on the same plants they’re already started eating.
Right now they’re small, but over the next few weeks they’ll grow exponentially into eating (and pooping) machines before spinning their silk cocoons. These first-brood caterpillars will emerge later this summer as part of the next generation this year.
Our native silk moths face increasing challenges from habitat fragmentation, outdoor lighting and loss of host plants. Because adult silk moths live such short lives and rely heavily on pheromones to find mates, fragmented populations can reduce genetic diversity over time. Raising and releasing moths in different areas is one small way people can help support healthy populations.
Another major issue is artificial lighting. Many moth species become confused and exhausted by outdoor lights, which can interfere with reproduction and make them more vulnerable to predators. One of the easiest ways to help moths is by placing outdoor lighting on motion sensors.
And of course, none of these moths can exist without the plants their caterpillars can eat, digest, and develop on. No host plant = no caterpillars = no silk moths.
To rear these soon-to-be mini-Heimlichs, we recommend placing them directly on a protected host plant outside using a butterfly sleeve (available here and at www.raisingbutterflies.org).
PLEASE snag a handout if you take caterpillars home, as it t answers many of the most common rearing questions. For additional questions as you go along, check out the Facebook group Lepidoptera Rearing 101 - Ohio. Our local “Caterpillar Guy,” KC Clark, is one of the moderators and an incredible resource.
We’ll be sharing 2–3 caterpillars of one species per family while they last.😊
Flit on by!
