I am super proud to report that Amy Hastings and I have been part of a wonderful collaboration with Noah Whiteman’s and Susanne Dobler’s labs reconstructing the evolutionary history of genetic changes in monarch butterflies experimentally (and in vivo) using fruit flies. You can read the paper, just published in Nature here.
Lots is being written about it, including the… Read more
The estimates of the monarch butterfly overwintering population were announced today (Wed. Jan. 30th 2019) by WWF Mexico. The butterflies are so dense at their dozen or so mountain-top clustering sites that overwintering butterflies cannot be counted individually. Instead, the area of forest that is densely coated with butterflies (at about 5,000 butterflies per square meter looking up into the… Read more
What to do about the decline of the monarchs? The recent Thanksgiving count in California was dire. The spiral in eastern north America is no better. The monarchs need many things, and milkweed is absolutely essential. It is the only plant their caterpillars eat. And as described in my book, Monarchs and Milkweed, the two share an intimate and antagonistic… Read more
I study caterpillars. But really whatever you study, if you are into it enough, becomes part of you. And eventually, those targets of our attention and love (and well, okay, our obsession), get their revenge. I’ve spent a lot of time on Monarchs and Milkweed, studying and contemplating their toxicity. Milkweeds make poisons, monarchs eat the milkweed (and eat nothing… Read more
Gail wrote in recently about a late season monarch here in Ithaca in mid-October… below is her Q and my A.
I found your email by searching Monarch and Cornell. I just found a large Monarch outside here in Ithaca. I brought it in b/c it was on the ground barely moving. Is there anything I can… Read more
In this post, you can see where former graduate student and postdoctoral members of our lab have ended up. Although all graduate students have been American or Canadian (and settled in North America), half of the past postdocs have been European and found their way back home.

I am sorry to miss this year’s Ecological Society of America meeting, currently ongoing in New Orleans. I lieu of ESA, next week I will be presenting at the International Society of Chemical Ecology meeting in Budapest. In addition, I am happy to report that Paul Metzler has produced a comic about last year’s meeting… one highlight is below.… Read more
Returning home after a year of sabbatical travels… it is great to be back in Ithaca, and a quick 30 minute survey of my garden revealed the intact milkweed-insect community. I promise to have the next post on Milkweeds (really Pachypodiums) and (African) Monarchs from Madagascar soon. But, for now, here is summer in the milkweed patch…… Read more
Just published in Science: a new perspective highlighting recent advances in our understanding the monarch butterfly’s declining population. Check it out here! See also commentary in today’s Washington Post.

Sabbatical is one of those remarkable gifts of the academy. At Cornell University, after 12 semesters of service on campus, one can apply for 1-2 semesters off campus, free from most administrative and teaching duties to focus on scholarship. This year has been my third sabbatical, and every one seems better than the last. I was unquestionably able to commune… Read more
Art, biodiversity, chilies, Danaus, and extremes… that’s what I’ve found on sabbatical here in Oaxaca.This is Part IV in my series from Mexico where I am based on sabbatical leave from Cornell (click here for the 3rd post). I’m following up on my recent book Monarchs and Milkweeds: A migrating butterfly, a poisonous plant, and their remarkable story of coevolution. … Read more
The first grant season of the year is over. I got a couple grants and did not get a few others. It always feels like a mixed bag of “that’s so exciting, I can now do ALL the research mwahahahaha” to “it’s ok, I can work around the lack of funding by [insert: collaboration, reduce sample size, get rid of… Read more
Greetings monarch and milkweed enthusiasts from Oaxaca! This is Part III in my series from Mexico where I am based on sabbatical leave from Cornell (see the second post here). This post follows up on observations here that are laying the foundation for my next research and writing projects, continuing on from my recent book Monarchs and Milkweeds.… Read more
Continuing with Q&A from insightful readers:
Chris Padgett of Louisville, KY, recently wrote: “Hello, I recently read your book. I’m curious, is Monsanto or a think tank funded by their industry funding your work? I ask because I find it interesting you suggest GMOs and pesticides are not harming the Monarchs. Hearing you say this in various interviews on YouTube,… Read more
Every couple of weeks I get a very interesting email message from somebody out there who has thought deeply about monarchs and milkweed. Especially since these exchanges can be insightful and relevant to questions others may be asking, I have decided to start sharing some of these exchanges. Below is a wonderful message from a freelance writer, William Hoover, of … Read more
Hello from Oaxaca! A few updates on monarchs and milkweed, February 2018…

See this great book review in American Entomologist
And finally, a bit of humor, I think. Illinois… Read more
I am getting settled in Oaxaca, on sabbatical leave from Cornell studying milkweeds and monarchs in Mexico. Here is my initial report on plants and insects from the first couple of weeks. The people, culture, food, and biodiversity have all met my expectations so far. What a great country! This is providing inspiration for the next chapter of what I… Read more

A brief update on Monarchs and Milkweed from Montana, Dec. 2017.
Monarchs and Milkweed has received the National Outdoor Book Award in the Nature and Environment Category.
Here is a fabulous book review of M&M written for the scientific journal Ecology written by Kelly Nail.
And finally, M&M made the top 10 list for the 2018 AAAS/Subaru Prize for… Read more
I recently came across a new study by a group of friends and colleagues that blew me away. Of all the environmental pollutants and nasty things we use to kill pests, who knew that fungicides (chemicals used to kill fungus) would become a problem for bumblebee pollinators. This study:
McArt, S. H., C. M. Urbanowicz, S. McCoshum, R. E.… Read more
I just received word from the Dean’s office in CALS that I have been appointed the James A. Perkins Professor of Environmental Studies at Cornell! This is a huge honor, and I am thrilled and excited.
Embarrassingly enough, I didn’t know who he was. J.A. Perkins, who passed away 20 years ago, was the 7th President of Cornell. Here is… Read more
Science education should start early! And as part of our collaborative NSF grant on milkweed genetics and ecology (with Georg Jander from BTI and Steve Broyles from Suny Cortland), we are implementing outreach projects in the K-12 Ithaca schools. Led by research support specialist, Amy Hastings, and inspired by a set of experiments by former postdoc Patty Jones, second graders… Read more
Things are going well on the sabbatical in Missoula, MT! On November 9th I will be speaking at a “friend-raiser” associated with the Montana Natural History Center and the Missoula Insectarium. And in December I will be speaking at Harvard’s Arnold Arboretum. Both talks will give an overview of monarchs and milkweed and an update on their current predicament. I… Read more
An excellent new study finds that climate, habitat loss (in both Mexico and the USA), disease, & insecticides contribute to decline of monarch butterflies. Although one could quibble with the emphasis placed on discussion of various issues, what I appreciate is the quantitative nature and comprehensiveness of the study, and the attempt to include as many factors as possible. Perhaps… Read more
Anurag and Jennifer are off for sabbatical for the 2017-18 academic year… but science in the lab continues. As a wrap-up, here are some news and happenings from the summer months…
Congrats to Jacob and Katie for passing their A-Exams with flying colors (see previous post on their cork-popping performances).
Anurag, Jacob, Katie, Lina, and Patty all attended the Ecological… Read more
On July 24th 2017, I set out with my family from Ithaca, NY, for year-long sabbatical leave from Cornell University. Our destination for the fall semester is Missoula, Montana, but our first major stop was a family visit in Urbana, IL. Given my travel companions, especially the kids Jasper (12) and Anna (8), we decided to take our time driving… Read more
As part of being the Vice President of the American Society of Naturalists, I had the opportunity to organize a symposium at the annual meeting in 2016 (Austin, TX). The topic was convergence, natural history, and the big questions in biology. The talks were great, and what I think (hope!) will really have an impact on the field is this… Read more
US agriculture is based on ideas that make me scratch my head. We typically grow plants that are not native to North America, we grow them as annuals, and we usually only care about one product from the crop, like the tomatoes that give us ketchup and pizza.
And we don’t like weeds. Why would we? They take resources… Read more
It’s peak season for milkweed and the village of insects that make milkweed its home. In my book on Monarchs and Milkweed, I devote an entire chapter to these diverse and fascinating other milkweed insects. Below are photos from two days last week (July 6 and 7th), one set from my front yard and the other from Shawangunk National Grassland… Read more
I recently had the opportunity to sit down with Paul Feeny, one of the all-time great scientists who studies plant-herbivores interactions. Paul has been at Cornell since 1967, and was one of the founders of the discipline of chemical ecology. Over the years Paul has had many successful students, he taught a range of courses, and contributed to the communal… Read more
