Spotting

Something very interesting going on, are they dancing,
wonderful sharing polerpress, thanks

thanks for posting the video!

That twitching in the video is further evidence that these aphids have been parasitized. I've seen the same behavior in parasitized caterpillars.

Hopes = holes. =)

This looks like aphids on wild mustard. The bigger, greyish aphids are called "mummies" because they have been parasitized by tiny wasp larvae. Sometimes you can find ones with little escape hopes where the wasps emerged after they pupated.
