Red larvae or aphids (?) found in the park on various plants
LuckyLogan-Thank you sooo much! I'll keep that in mind and will get at least one wide-angle shot of the host plant in the future to help narrow it down. :-)))
Yep, many insects only live on host plants. Aphids like these Oleander Aphids only feed on milk weed. http://www.projectnoah.org/spottings/372... There are over 300 species of aphid in Minnesota and knowing which plant they are on really narrows it down.
LuckyLogan-Hmmm I don't think so. I think at the time I was focused on just the little red bugs, not the plant itself. I know the plants though and could try finding them again this summer. The aphids are usually thick on them. Does the plant species help identify the species of aphid then?
These are aphids. Do you have a better picture of the plants that they were on?
