Cecropia parasites

I believe these are parasites or parasitoids on the back of a cecropia caterpillar near its last instar. If so, can I remove them, or is that futile? I would appreciate any help.

Moved from Tachinidae.

These are indeed
parasitoids, eggs of a tachind fly. If allowed to hatch they will kill the caterpillar. They can't be removed without damaging the cat, but the good news is that they can be destroyed. Simply prick them with a fine needle, insect pin, or watchmakers forceps. Work sideways so as not to pierce the cat skin. Take out as much of the egg contents as possible.

I luckily came across this at
I luckily came across this at a decent time; I'm having techinid problems of my own. I have a C. regalis with some aggs and tried the needle thing. How do you know whether it worked?
