There are long legged species. I don't know which species are long legged though.
Here is what I know.
A. cockerelli is harvesters.
A. cockerelli, A. fulva and A. rudis are found in Ontario for sure
Their larvae are very active and they are not fed mouth to mouth. Rather larvae will actively eat on their own once a food source is placed near them.
... That's pretty much it. Not much info is out there.
