ITIS lists Isoperlinae under Perlodidae, but Chloroperlinae under Chloroperlidae. Are you saying that some of the images are not Isoperlinae? We're not certain which images belong under Isoperlinae and which need to be moved. Can you clarify?
We moved the two you had clearly identified, but don't know if all the rest of the Isoperlinae are fine.

Historically I believe that the chloroperlids (as Chloroperlinae) were once part of the Perlodidae, but they have been set aside as a separate family for some time now. All the other images under Perlodidae look to be correctly placed in the family, probably Isoperlinae but I will not make that judgment - they could be members of the Perlodinae. At least some of the "green-winged stoneflies" (subfamily Isoperlinae)do have a yellowish/greenish anterior margin to the forewing, but never do they have the entire wing a brilliant green, as do the "green stoneflies," the common name for the Chloroperlidae. The current classification is at

I've seen snow crickets and they are cool bugs! ^__^ -I don't think it's one of those-with some more looking here I think it looks rather like a Isoperlinae - Green-Winged Stonefly. But I've not seen one so green.

Definitely a stonefly, and probably indeed an isoperlid.
