These are the cocoons of a Chalcid wasp in the genus Eulophus. They are ectoparasitoids of caterpillars. The wasps themselves are tiny. The red cocoons with the little pile of feces (the yellow stuff) makes for a visually attractive (I think) image.
Sans doute ces cocons étaient bien cachés et c’est très intéressant de la voir.

Amazing photo and ID Christine. I looked the genus up on Bugguide and they have some excellent photos as well including photo series showing the larvae on the host caterpillar, the pupae and then the adults as they emerge from the pupae. Unfortunately I cant leave a hyperlink on this comment site. Claudia
