Monarchs are locked in a battle with Ophryocystis elektroscirrha (OE, a parasite that can trap a butterfly in its own chrysalis and deform its beautiful wings. Turns out there is a wrong way, and a right way, for you to help these butterflies in your backyard

Sorry, but I'm high key frustrated with some of the information in this video. I grow tropical milkweed in my patio garden for the monarchs. Of the 2 dozen I raised this year, I lost half to tachinid flies, but not a single OE. I grew local narrowleaf milkweed 2 years ago, but the problem is that because of climate change, monarchs showed up this year in February. My narrowleaf milkweed was still dormant underground until June. Please tell me how monarchs are supposed to go 4 months without local supply? True, local milkweed dies back in the cold, taking the OE spores away. The same thing happens to the tropical milkweed when all the new growth gets eaten down the sticks and I physically cut the plant down to a stump 3-4x a year and the sticks go to the green bin. Also, the monarchs in Western region where I live annually overwinter along the California coast. So, what would the disruption in migration cycle be? If anything, climate change has been the biggest disruption. Tropical milkweed is the earliest available milkweed in these changing climates for monarchs awakening from diapause early and can be managed responsibly to reduce OE spores. I'm keeping them around.

can yall STOP saying how terrible! humanity is bad! and stuff like that. if you want a change, then join us who ALREADY have been doing this for years and order your darn natives. heres my guide: narrowleaf milkweed and showy milkweed (asclepias fascicularis and asclepias speciosa) are for the west. common milkweed, swamp milkweed, and butterfly milkweed for the east (asclepias syriaca, asclepias incarnata, asclepias tuberosa. wouldnt suggest butterfly milkweed though as it has the least amount of toxins in the entire milkweed family and you are far less likely to get eggs, as well as butterflies with good toxins. on the bright side it is easy to get and can be a very good emergency food source for caterpillars if the other plants have no leaves.

I live in New Mexico and my tropical milkweed dies back to the ground completely as soon as it gets cold. So, your blanket statement about tropical milkweed is not entirely true. It may be true in southern regions that tropical milkweed does not die back, but any place that gets freezing temps is going to see their tropical milkweed also die back.
It would be helpful for people to know and understand that there are non-migratory monarchs that live in southern Florida with heavy oe spore loads and they carry on and live very normally. This is not a simple, easy issue and scientists have been studying it for some time, but don't always tell us the WHOLE truth, but enough to serve their purposes.

I discovered OE this summer when I found a butterfly with a crumpled wing. It could not fly so I let it sit on my arm for a while. The poor thing never wanted to leave my side and it lived for about a week and a half in my garden. I was so sad about my new butterfly friend so i researched OE and decided to help out by planting tons of native milkweed and raising my own monarchs. I found 3 OE infested butterflies with crumpled wings this year, I hope we can find a way to eliminate the parasite soon.
reply

I have raised and released hundreds of monarchs. This is what i always tell people when they think about raising them. Its not just housing them, giving them food and letting them go. Its about providing yourself with proper knowledge to raise them, otherwise their better off being outside.
OE is viscous and so cruel. The best, and only thing you should do for a butterfly with OE is to humanely put them down (freezing is a great humane method where they get put to sleep gently, it is not painful)

Doesn't make sense, wouldn't migrating butterflies bring the parasite with them and infect all the migrating butterflies anyways? And monarch aren't just a temperate north american species anyway, but people in usa are ignorant of this, their range includes much of the tropics as well all the way into south america, so this parasite cannot be such a threat to them, just a part of nature.
reply

From the caterpillars beginning eating it's own shell to the release of the butterflies screams at us the evidence of a Designer.
But why have we been given so much evidence of a Designer, surely there must be a point to All this, such discovery isn't without reason, the more technology we aquire the more we discover at micro levels of each tiny species.

In Mexico it's other thing. Literally NO ONE sells native Asclepias (Milkweeds, and the Tropical Milkweed is the only type that people sell in various places. and it is actually native of some parts of Mexico, but people don't really care about it, and now we have lost the knowledge of what's ACTUALLY native and what's ACTUALLY not. but in Mexico City is even worse.

Hey deep look! Can u make a topic on Cigarette Beetles? I just started to notice these little guys around the house, as i look up on them, theres not much research on them but say like they eat bread but mostly unsure whether or not if theyre a good or bad pests like fleas, bedbugs or cockroaches. Would be appreciated so we can know more about these house pests: 3
reply

I feel like I'm missing a lot of info still after watching this. How do these infections start in the first place? There's no like larger parasite that can go around infecting stuff so. where did it come from?
And when the milkweed dies does that make all the old oe die also i guess obviously?

reply

Amazing footage, and you did a fantastic job explaining the biology and emphasizing the need to plant native milkweed for monarchs. It's so important to create diverse and healthy habitats for butterflies and other insect species and the complex web of species they interact with.
reply

Every November I cut my milkweed but I tried growing native milkweed. it's insanely difficult. if it weren't for the tropical milkweed I think these things would be extinct. Thanks to the tropical milkweed my grandmother probably raised over 1000 caterpillars.
reply

Thank you for posting this information! We raise black swallowtail caterpillars here, but were wanting to start planting milkweed for monarchs as well, since they occasionally fly into our yard as well. This is good stuff to know for when we begin!
reply

Kinda sad that they almost hit endangered levels during the Monterrey, Mexico freezing temperatures which it was a very harsh hit for everyone. I think it was in 2017 or 2018. It made me sad and thankfully many people are getting milkweed plants
reply

Scary indeed. That could potentially cause extinction of a species, or already happened anywhere else in the history?
This is a very interesting footage. Researchers have made a great job! So did deeplook. Thanks.

reply

Where is Laura and who is this random woman telling me what types of milkweed to use? Hey wretched shriek of a voice lady, you're cramping DEEP LOOK harder than those parasites are cramping monarchs from flying.
reply

I have a few milkweed plants come up in my yard every year. for the last 3 - 4 years now. They are native too. I have to protect them cause everyone else in the family wants them gone cause they're weeds.
reply

When the butterflies were struggling to get out of the chrysalis, I was worried that the butterflies could potentially rip off their abdomen from their bodies, while they're trying to escape
reply

look at the poor deformed butterfly.
other butterfly born perfect and fly happily on the air
while we born disability had waste time to be born on earth
born to be suffering
so sad.

reply

I just ordered some milkweed seeds, but before clicking on the first one I saw, I checked a few websites about the milkweed native to my area just in case the popular ones were a problem.
reply

Learning about AS much as possible, I STARTED growing milkweed last year and I have seen two caterpillars eating the leaves! I only saw one parent so NEXT year hoping to see more every year!
reply

to understand this one must know why do people plant milkweed and what is it for?
that i want to know. if it is just for show pretty-ing your garden only then you can do without it.

reply

And they were trying to blame us for the reduced population of the monarchs. Most likely it was one of the scientists who brought in the parasite when they planted the milkweeds.
reply

Heres a fact: Butterflies can remember things that happened when they were caterpillars, because even though their bodies change their brains dont and they retain their memories
reply

Oof that was hard to watch for some reason, seeing the butterfly just decimated like that! Thanks for bringing this to my attention as I had no idea about this parasite.
reply

Since I was born. 32 SHORT years ago. Just kidding. I claim 25. Forever. Anyway. I was told I was allergic to butterflies because they have sulfa on their wings
reply

Wait but how do the parasites reproduce then? It seems such an ineffective way, considering a lot of the infected monarchs will never get to lay eggs to continue the cycle
reply

Yikes. I planted the tropical in my yard in the spring, and two of our monarchs we had in a habitat had deformed wings. Guess I should go take it out of the ground!
reply

This is incredible. Our touch is felt across the natural world. Sometimes it's soft but most of the time it's like a hammer. When will we learn? My take is. never.
reply

Stop planting your plants or you will end up like us, we brought in Cane Toads to Australian, and well, that didn't go well. (Also Foxes, etc etc etc etc etc etc)
