Monarch chrysalis parasitized by two pupal parasitoids 

siresly were not even insects these pariliz insects only do that on old day catapilars

At that time,he is more like a 12th grader. If we match ages with caterpillars.

is why you dont let someone lock you up with 2 parasitic insects in the same room

Amen. Step 1, lock your doors so no criminals like these jokers get in. Step 2, do your crunches daily so if the locks fail, youre still sittin pretty w a six pack... Cuz you know, an awesome six pack is all it takes to keep the predators away. Isnt that right Hollywood?

@@kittycatlover5610 1. Your grammar sucks 2. Shut the fuck up 3. Grow up 4. Eat dirt

Shade That Demon Cat Roaches don't have larvae 😂

Well, arguing with snowflakes are like reasoning with earthworms.

Debbie Quintero We must see it to learn from it.

It's for educational purposes :P but yea, I get what you're saying

forget it lol. rude

Grow up please

he needed youtube content

those are tachinid flies........

Diane Godbout oh you think we should spray pesticides on chrysalis, and how do we know these thing coming in to kill them, they are very tiny to see, I am raising 25 monarchs myself

Stephanie Lane we have reared over 200 Monarchs this year from egg to butterfly and we have lost exactly 2 both due to a caterpillar attacking a “J” It’s all about nature and the stupidity of humans who destroy their only food source (milk weed) we go near and far to find milk weed and also grow our own. The ones we find we wash with a bleach water rinse. No parasites passing from the leaves

@Silva Silva777 Is science, you always hating on people because of your stupid way to defend animals, people like you defend any shit instead of real agression to animals

You guys have been very harsh with him. Let's just say that this video looks kinda BS to me because this experiment has already been done. We already know how it works and tbh this looks like kinda a free and purposeless horrible death for that poor butterfly... It doesn't really look like science to me. Then again, I won't cry for a butterfly.

@@Ph34121307 Anyway only one experiment is not enough to learn about the parasite, if we want to protect this butterflies we most study this parasite and find a way to prevent extincion and at the same time, don't cause to the wasps any problem or ar least control the number

Yeah, sorry about that :)

The music seems to be in sync of what's happening in the video in a few instances though, and it has that 'something bad is coming' sound too, which is what's happening.

The chub you chase LMAO

Lol, ya! He felt the tiny antenna touch him, they are very sensitive!

for your milkweeds you post to check for small bugs with a 🔍and then bring it inside away from other animals in also love monarch caterpillar🐛I find them cute.

You just need about 15 potted milkweed plants in 1 gallon pots and need a simple 60 sized screen cage that you can put the small caterpillars on. But that's after you collect the fresh eggs from the plants out in the wild and keep them in small container until they start to emerge, then put them on the well protected plants. It's really the only way to do it anymore with all the dangers that oppose them.

I live in Florida and I just started raising Monarchs on my porch. I have two chrysalis. On one of them I found something black attached. How I would know is that wasp? I didn't see any flying bugs I took picture of it. I had so many, most of them end up dying. I’m wondering WHY??? It is heartbreaking. How can I protect them. Mr. Carl Stenoien please help. Which kind of protective nylon stocking and where I can get it?

@@victorialucci6163 Just buy the kind of nylon stockings women use.

+Kelly Hoerter I did know that this would likely happen. I set up this video in a 1 cubic foot cage in our lab. I study interactions between monarchs and these parasitoids as a graduate student researcher at the University of Minnesota. Keep learning guys!

Bruh chill, people need to know this, and this happens all the time in the wild

@Silva Silva777 Yeah, we should ban all research and just let the wasps wipe out monarchs fuck the cistem

@@CarlStenoien and it's cruel!!! It's bad enough their numbers are dangerously low let alone you killing them on purpose for your classroom!!!

@@majinbuu345 people already know this, and this species has been declining rapidly for years. Such a waste.

Chill, they need to study this, it's important

Sandy Blanket I agree. Makes me sad to see this

Sandy Blanket you mean caterpillar .

its what happens in nature and its for documentation on what it does

Sandy Blanket meow!

It’s a little upsetting but if it’s only I’ll be little happy only one died to these monsters

Positron Decay Its a subconscious thing. All living things do that. It’s like you feel something on your arm and you either shake it or hit it.

That’s the caterpillar turning into a chrysalis and shedding the old caterpillar skin. That is their normal development.

I can talk about that in a video. Parasitic wasps.

Great questions! Under lab conditions, the wasps do not seem to discriminate between tachinid-parasitized and non-parasitized hosts, though I have not conducted (not am I aware of) any large-scale experiments to address this question. To your second question, monarchs sometimes survive parasitism attempts by these wasps in lab experiments, and it may be related to the number of eggs placed by the parasitoid. In other closely related species of parasitoids and butterfly hosts, experimentally shortened oviposition bouts of ~1 hour or less increases the chances of butterfly survival.

It is, there are many variations out there. I had some thst looked like fruit flies (without a bee head shape).

It never snows over here -_-

Nevermind.

The wasps can fit through regular window screen, so you must rear them in containers with small air holes or use very fine mesh.

You just need a big rectangular (4'x3'x4' ish) cage built with 2x2 pieces of wood with double layered netting from Walmart , its 97cents a yard, so you can afford to even triple layer it because it's so cheap and it will definitely keep everything out. It doesn't have to be pretty, just has to be completely sealed. It's better to collect the eggs early and keep them in containers until the hatch and then put them on the plants that are inside the cage, or have potted plants out in the open and when they have a few eggs on them, move the whole pot inside the cage for protection, but you must have a mini broom to sweep off the pot entirely, especially under the rim or handles, don't let any spider hitch a ride in that cage. There's some maintenance involved, but this will give you a 99% success rate in raising them, your only concern will be making sure you don't run out of milkweed. I mean you're pretty much flipping the success rate of these guys around with a double, triple layered screen/netting cage, so your milkweed will go very fast.

Why do you raise pest

Where are you located, Debbie? Would you be willing to share details with me via email? I'm compiling geographic records of parasitism (as well as other details) to try to learn more about this interaction.

You have to bring them inside and raise them.

For SCIENCE

Mischievous Vagabonds so hes a scientist??..

@@Droppingineveryvideo studying to be one I believe

??? This is a lab experiment to see what happens when you mix the two. If you interfere, you mess your experiment up

Steven Preston, We already know what happens and it’s devastating to the monarchs. They shouldn’t need to purposely allow it to happen for a video. We should be trying save and protect every monarch caterpillar we can.

If you touch the wasps, they may might sting you.

PenFTW the Necrozma 2007, if you don't know what you are talking about, don't talk at all. This wasp hasn't got a stinger, it is a parasitoid.
