I was wondering what those were, I have a bunch of red ones on a plant in my backyard here in MN, they are only on that one plant though.

They are also called ant cows - which is fitting since they are on a milkweed.:lol:

Nice shot. I don't know if aphids are a downside, though, as they do attract other photogenic insects as well. This past Christmas one of my father's bushes was covered in aphids and was also full of yellow jackets and ladybugs that were interested in the aphids enough to ignore me photographing them.

Fisheye1:

Most aphids are green (the black ones in the picture are a different stagein the reproductive cycle); these are the first yellow ones I recall seeing, but then I seldom look. I have heard it said that they can adopt the colors of the flowers of the plants they are on, but I cannot vouch for that - the aphids on our red milkweeds are yellow, too, like the ones on the yellow milkweeds. Spider mites are red - can you get a picture of your red aphids?

Tim:

The other bushes in my yard have been full of birds gleaning aphids and psyllids, but nothing seems to bother the aphids on the milkweeds - maybe they have a noxious taste, like the milkweeds do. The only things besides ants (which farm the aphids) on these milkweeds are Monarch butterfly caterpillars which carry the bad taste into adulthood to keep the birds from eating them - nothing bothers the caterpillars, either.

Thanks for looking and commenting.

One stagedoes havewings - these are the ones (the black ones in the photograph may be shed skins or dead ones)that reproduce sexually and lay eggsthat produce the wingless ones, whichare all parthenogenetic females producing living young that do the same. I need to review ths to make sure it is correct, but still it is one of the stranger life cycles in nature.

Here is a winged one. Same setup as above, with added 1:1 adapter. Top of the stem in in sun, the aphid in shade. The small silvery ones are completely transparent early instars (immature stages).

This one is better. Note the stomaches inside the immature instars nest to the winged one.
