Red Aphids- Genus Uroleucon?



This year, I haven't found any of the yellow colored, non-native Oleander aphids, but we do have a fairly nice colony of these red aphids.  Perhaps these belong to the genus Uroleucon?  It seems there isn't much information readily available about aphids. Perhaps aphids are the next big thing.  Do I see a aphidapalooza festival in the future? Probably not, but they are fascinating creatures, though. These individuals are feasting on my double flowered green-headed coneflower, Rudbeckia laciniata 'Hortensia'.  This Victorian era "heirloom perennial" has been passed through our family- our clone originated from relatives in northeast Indiana.  Calling it an heirloom perennial seems to be a bit out of place, however, since I also read that it was affectionately known as "the outhouse plant".

  1. Hello, I have these on my rudbeckia as well, I'm in St Paul, MN. Do you know if they are pest or beneficial?

    1. In my book, they're all beneficial!
