When I reared caterpillars outdoors I had to keep them under netting to protect them from these pests. Once I found a sphinx caterpillar with a couple of Tachinidae eggs attached, so I scraped them off.
@@Tatusiek_1 some of them are actually good for agricolture because the adult butterfly is a pollinator while the larval stage doesn't eat that much, like the Papilio machaon in this video.
@eggrollsoup not ALL caterpillars are bad. You have to take time to think about the beautiful butterfly or moth it will become if you just don't kill it. Also you have to remember that more pesky flies will be flying around your house if you invite them.
I reared Papilio canadensis and despite a careful inspection lost 6 of 7 pupa, you won't find this or many other butterflies anywhere near a Landfill operation, way too many flies. Any dog-parks have the same effect. My paper was called, Tactics of Tachnid fly on P. canadensis. It reached someone in Brisbane, where 6 species of Swallowtail are now lost in the dump sites.
Larva completed the process inside the butterfly and tried to get out, but because it was in the cocoon it did not succeed and died! This is fascinating, but at the same time very bizarre!
I've reared monarch caterpillars. One of them went "limp" while hung up in preparation for pupation, and three maggots emerged from its side. Another one became a chrysalis, but unusual color patterns developed, and then maggots emerged from it. In both cases tachinid flies developed from these maggots.
@James Merryman Thanks for pointing this out. I imagine by that stage, the tachinid larvae either "know" what not to eat (to keep the remainder alive) or it is so close to the time they will leave the pupa that this (keeping the pupa alive) is no longer a necessity.
@James Merryman Thanks for the additional information. I've never reared hornworms although I've seen a few having braconid cocoons. You're certainly correct about delays in eclosion resulting in wing expansion problems. I've also seen that "helping" an insect (such as a lep, a wasp or a cicada) emerge can result in improper expansion, or even a complete lack of it. (Of course wasps typically expand their wings while still in their cocoons, but I've taken pupae out of their cocoons and seen this--if the pupa is essentially mature, it will expand properly but if too early, it is likely to have problems, with vespines being more susceptible than Polistes.) I've learned that collecting cicadas while eclosing is a very delicate operation, particularly from the time the nymph becomes immobile until the adult does its "flip" to extricate its abdomen from the nymphal shell.
Fortunately, here in San Diego, California I have never witnessed a Tachinid parasitism of a swallowtail caterpillar but the endangered Monarch is decimated by this evil filth of an insect. I have been unable to pin the evil fly on Big Ag but were I to do so, I'd look into suing.
What happened!! I was watching until the end and then??? I have a monarch chrysalis now that had a thread green goo and dark spots. I think it's hosting a Tachinidae. Isolated it and gonna watch what happens but I'm biased toward the Monarch. I want to end its suffering but then, from a fly perspective, it's new life so I'll watch now that I see the fly is also an amazing creature. Amazing video.
I would have pulled that life-sucking pest out with a pair of tweezers and hope the monarch heals. I consider flies as simply pet food for lizards I used to catch. I would hold on to them in a big terrarium for a couple weeks then release them back to where I caught them.
I hate the Tachind fly so much, oit if 50 caterpillars the killed 42, i try to put the new eggs under cover as soon as they hatch, but the flies get them early and lay their eggs. I know because i open the dead body and the fly larvae is in there alive. Natures biggest mistake, the tachinid fly.
Reminds me how a species of the fly targets spiders. Unfortunately same spiders also fall prey to spider wasps, and the maggots get eaten by the wasp larvae and the adult flies get stuck and die inside the wasp lair
I wonder what happens to the caterpillar later? Is there a video about it?

how did it go? Did the caterpillar survive?

Congratulations, first time i have seen the fly at the time of laying her eggs. Extraordinary video indeed.
Thanks for your positive input!

I didn't like fly it's irritating
Nice video I never expected the swallowtail will take that from a fly hope to see another video with a different caterpillars
Congratulation, now I saw this event the first time. A great video ! 👍👍👍
This is the first time I have EVER seen a tachinid fly come out of an adult butterfly. I always see it in the caterpillar or pupa, but never the adult

Does the fly get dopamine when it does this?

Connaitre la nature des insectes. Impressionant.
I always understand only wasp lay egg on living thing.
but larvae didn't survive?
Now how does the caterpillar not feel the fly's ovipositor penetrating its skin?!

In orange orchard these flies are valued because they can contain caterpillar outbreak.
@@CP-jk3tc well the opposite of an outbreak is happening with monarchs right now! They're going slowly to extinction, as they are endangered
where are the flies?

Show more of full attacking
would like to see a house fly vs monarch caterpillar next video.
House flies don't attack monarch caterpillars. There are small tachinid flies that resemble house flies that do the attacking.
Monarch butterfly are toxic for parasitoids and predator
i'm surprised it survived maybe something killed the fly larva
@James Merryman poor thing as long as it lived and survived is a good thing
@James Merryman thats amazing
