Story time, a while back, I found a chrysalis, I wanted to see inside of it, so sadly I took it down and opened it with some small tools. I opened the chrysalis, and it was filled with countless tiny larvae. I was baffled and was amazing at what I was looking at, I further opened the chrysalis to see more larvae. For days I tried researching what was in the chrysalis, and I started to doubt if it was a chrysalis in the first place (because I’m no insect person). But finally after around 6 weeks I randomly stumbled upon this video. This video answered my question to what those larvae where doing in a chrysalis. Thank you so much for solving my suspicions. Great video.

I raised 13 monarchs in my house 3 years ago and 2 got bitten by the parasitoids. I must have brought the nasty parasitoid in when I brought in fresh milweed for the caterpillars to eat. So heartbreaking when this happens and a tiny worm pops out and hangs from the chryalis. Very disturbing to see how vulnerable monarchs are.

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.

[@pipevinepete7040]

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.

Carl Stenoien I've been wanting to know this for years, but do you know if these little wasps will still infect a fresh pupa after it had already been infected by a Tachinid fly, and also, can a Monarch still survive if it only had 1 or 2 eggs injected in it from one of these wasps, being that they're so small? Thanks for your time.

[@CarlStenoien]

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.

[@keiibo9006]

ok but WHY would you keep the chrysalis in there with the wasps? they are ENDANGERED and need literally all the help they can get.. i raised 11 in a cage and only 4 were even released as butterflies....

So this is not a chalcid wasp? I know that the larva will eat the non-essential parts of the monarch chrysalis. As I observe the wasp and the location it chooses to oviposit, it appears that the abdomen is the area of choice. I’m going to deduce from this, that the part of the monarch chrysalis with the most non-essential parts is located in the abdomen. True? False? Great video.

[@mister8800]

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.
