Dale, My pleasure! Glad I could help.
As part of my role at Harvard, I offer such services frequently to our museums, libraries, and all other affiliated units and personnel. For simple (from my perspective) tasks such as this one, I’m happy to offer my insights and guidance. I’m occasionally asked to assess past, current, or future pest issues in (non-Harvard) museums, libraries, manufacturing / medical / educational / etc. facilities. For those kinds of pursuits, I provide services through my independent resource, IdentifyUS LLC<https://identify.us.com/>. May you never have need for my services.

Thank you. Having someone knowledgeable guide us through the differentiating features of tiny insects - particularly the wings and antennae - will likely help scores of conservators like me, make better searching decisions. Appreciate you! Dale Kronkright Head of Conservation Georgia O'Keeffe Museum Santa Fe, NM On Wednesday, August 3, 2022 at 2:48:00 PM UTC-6 Pollack, Richard J wrote: 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?

They are about the size of book lice / clover mites.
