Globular Springtails - Sminthurinus quadrimaculatus
Ballston Lake, Saratoga County, New York, USA
Size: barely visible
These critters were found on my indoor cactus plants. They have been on them for years, and cause feeding damage. I haven't been able to get rid of them. ID help appreciated.

Well done, Harsi.
The larger ones indeed match quite well with S. quadrimaculatus forma bimaculatus.
The smaller ones are too much out of focus to check whether or not it are juvenile Sminthurinus or mites...

Karl, if you disturb the springtails with a fine hair or so, they certainly will jump away.

Springtails?
I'm still at the beginner's end of the learning curve here, but I'm thinking that at least the larger insects you pictured are not mites, but actually Globular Springtails (Order Symphypleona). Here's a species that looks strikingly similar to your images:



I am only guessing at this point and you should wait for confirmation. Fortunately, there is a wonderful springtail expert on this site who will undoubtedly comment eventually.

Looks like a match
Yup, that sure looks like them, although these guys don't jump. Thanks.
