We keep getting calls about the different caterpillars or bugs on peoples milkweed plants. Milkweed feeds many different insects and as long as those insects aren’t eating the monarch caterpillars all is good.
Every year around this time, I see a familiar thread pop up in native plant, gardening, and pollinator groups. Concern, confusion, and sometimes panic when people spot caterpillars on their milkweed that are not monarchs.
I understand the instinct. We care deeply about monarchs. We plant milkweed for them. We wait for them. We celebrate every egg and caterpillar. So when something unfamiliar shows up, the reaction is often to remove it, squash it, or spray.
But here is the deeper truth. Native gardening is not about control. It is about connection.
When we plant native species like milkweed, we are stepping into an ancient and complex web of life. Milkweed has always been home to far more than just the monarch. The yellow and black caterpillar you are seeing? It is likely the milkweed tussock moth. It relies on milkweed to complete its life cycle and has coexisted with monarchs for a very, very long time.
Milkweed also supports red milkweed beetles, large and small milkweed bugs, aphids, and even predators and parasites like wasps and flies that help keep populations in balance. Some feed on the plant directly. Others live and hunt among its leaves.
It can get messy. It is real, and it is the sign of a functional ecosystem. This is not pest damage. This is purpose.
If we only want our milkweed to look pristine or to host monarchs and nothing else, we are missing the bigger picture. Native plants do not exist to serve a single species. They support communities, entire systems of life we may never fully see or understand.
We can love monarchs and make room for other creatures. We can sit in wonder at a plant’s ability to feed, shelter, and sustain so many beings. Not just the ones we have decided are worth saving.
Native gardening is an act of humility. It is a reminder that we are not the architects of nature. We are guests. We are stewards. And sometimes, the best thing we can do is simply let it be.
So this season, if you see a new caterpillar munching on your milkweed, pause before reaching for the spray. Take a photo. Look it up. Ask. Learn. And consider this...maybe what you are witnessing is not a problem at all, but the very reason you planted milkweed in the first place.
