Parasits!

2# 3# - Buquetia musca aka Tachina Fly
4# 5# - From Ichneumonoidea Family Aka ichneumon wasps



Long time ago I’ve seen 3 cocoons ( You can see them here [photoblog.com]) and I couldn’t resist in saving them to see which butterfly would hatch from each! I saved them in transparent boxes and I’ve put them near my desktop, so every day I’d know if something happened! Some days ago, I got surprised when one of the little cocoons, had been eaten by a maggot, and I discover that the cocoon(well not exactly the cocoon but the caterpillar) had been infected by a Tachina fly! These flies are very similar to flesh flies, as you can see on the picture. Ok, I got shocked, but I was ok, because I knew I had still 2 more to see! I pic up the tachina fly pupa more the eaten cocoon, to a separate box, so when the tachina fly hatched I’d also photograph it. All was fine till yesterday. The tachina fly hatched, and those are the shots! But in the same day, in the other box, the other little cocoon hatched too! But it was not a butterfly, but a bunch of 10 or more , little ichneumon wasps! One of this wasps (the mother) infected the caterpillar while she was alive, and then when she was on the cocoon, these wasps had eaten alive the poor caterpillar! Now is only left the big cocoon! I just hope it at least is not infected with some parasite! As for now I’ll never know which butterfly was on the little cocoons! :(

I apologize for the quality of these shots. First because they were taken with low light, and especially the little wasps were not more than 3 mm!

Ricky I totally support you in your close observations of nature. Ted is getting his knickers in a twist, but don't worry, I think we all know that you are a true lover of insects and would never make cruel experiments on them.

Nop Ted! I didn't Interfear with Nothing! I saved the cocoons to see what they would hatch! and then i'd let them go!
As I've said, the parasite already infected them when they were caterpillars! so I cant do anything!
The insects that hatched, I didn't kill any of them, i let them go free. I thought they would hatch butterflies and not parasits!

I saved the cocoons, once where they were they would be killed by my parents, since they were in my house, and I'm sure they would do it. Besides that, they would survive, because the places where they were were very comuflated!

My Experiment was to see which butterfly would hatch from that cocoon only! after it hatch i'd let it go!

Tell me Ted what is wrong with this?
