Dale, Sure! Independently (and together), the features that would discriminate thrips from springtails would include:
* Body shape: Whereas some kinds of springtails to have a bulbous posterior, their body profile is considerably different than that from a thrips. There’s a much more distinct separation between head and thorax and thorax and abdomen here. * Antennae: Note the fine / narrow antenna here, and compare to the wider antennal segments of a springtail. * Wings: Springtails go airborne (briefly) because of the release of their ventral furcula (springlike lever), they never develop wings. The imaged creatures have wings (but not all thrips are winged). There’s more, but that comes from more than a few decades of looking at little beasties. Does this help? -Rich Richard J.

Those are also related to fungi in deteriorated plant debris and not directly harmful to collections - although are usually around in numbers great enough to sustain damaging carpet and furniture beetle larvae. Richard- can you please describe what lead you to conclude thrips rather than springtails?
