Milkweed and its Insects

- Milkweed is a challenging plant to eat. It is covered with hairs, contains a sticky, gummy latex, and is highly toxic. Yet there are a variety of insects that are specialists on feeding on milkweed. The caterpillar of the monarch butterfly is the most famous.
Anurag Agrawal shares his research on the relationship between milkweed and the insects that rely on it.
Agrawal is an associate professor in the Department of Ecology and Evolutionary Biology and the Department of Entomology. He is also the director of the Cornell Chemical Ecology Group and an associate director of the Cornell Center for a Sustainable Future.
I'm in Southern CA, Orange County. I've lived here for 42 years since birth and at my families house we always had these weird red bugs in the dirt. The house is located in an area that used to be very healthy wetlands. Anyways, we never had milkweed (i mean us as a property, I'm sure there was milkweed here before all the development)but as soon as I got some plants those red bugs in the dirt moved onto the milkweed. Turns out they were MILKWEED BUGS! Living in the dirt for DECADES until their milkweed finally came back! Pretty crazy
Great informative video.
Great footage and information. Thank you!
Fascinating information about the challenges the monarch caterpillar 🐛 overcomes to get a meal from milkweed. Too bad that glyphosate disturbs this ballet of survival. God created everything very good even to their abilities to adapt to each other. But we who have more than instinct to go on need to consciously not destroy a beautifully functioning system.🐛🌿🌼🦋
I truly wish someone would do a study comparing the 2 varieties of milkweed, northern and southern only, as they different so greatly. I also study milkweed in South FL, aphids my biggest issue, some red bugs, but grow back is critical for me as I use it in my habitat. My cats have never made it to pupa if left outside. This is also a study, wasps? anoles? birds? And why am I discussing this if the caterpillars are toxic themselves? help!!!?
Thank You.
Good Job
Awesome presentation...Thank You
I've been growing milkweed for five years and this is the first year I've not seen ONE Monarch Butterfly.It seems to me there has been a colony collapse this year.DO YOU NO ABOUT THIS? PS Nor have I seen ONE HONEY BEE this year. I live in Peterbourough Ont. Canada. Please reply, thanks you, from Andycap
