These are great, I would add that with a scale reference you could do basic morphometrics on a lot of the taxa. I also think they would be a great resource for training/testing students and techs that process these kinds of samples. The resolution is high enough that, for example, orabitid mites are clearly distinguishable. The best ones are in petri dishes without non-invertebrate material but even the ones with plant litter are worth perusing. This is something NEON should do with their by-catch if they are not already doing it. The LSAM Project are too messy to be that helpful, although it was good that they posted them.

Subject: Collection Residues (By-catch)
We've posted photographs of residue specimens (by-catch) that have recently been incorporated into the Clemson University Arthropod Collection (CUAC).
Brooks Samples (Malaise) - Residues
Specimens were collected as part of:
Brooks, J. D., S. C. Loeb, and P. D. Gerard. 2017. Effect of forest opening characteristics, prey abundance, and environmental factors on bat activity in the Southern Appalachians. Forest Ecology and Management 400: 19–27. http://dx.doi.org/10.1016/j.
Leaf Litter (Berlese) - Residues
A hodgepodge of residues from leaf litter samples taken mostly in the eastern US. Most have been scoured for beetles, although a few samples are coleopteriferous.
Like any specimens at CUAC, these are available to visitors for study. Loan requests for specimens to be shipped, either sorted from the residue sample or the entire sample for specimen extraction, will be considered on a case by case basis. Persons interested in volunteering to visit CUAC and sort specimens (or order, family, etc.) are welcomed!
Long term vision:
These photographs represent the first steps in creating a process that will lead to the following scenario:
1. Photograph of residue sample uploaded to public site.
2. Relevant information entered, especially: locality, date, collection technique, institution.
3. Public users can tag specimens (either point or outline) within the image with identifications.
4. Photos can be searched based on locality, date, collection technique, and taxon.
The end result is that researchers can search for taxa of interest and (perhaps) orphaned taxa (thrips, Psocoptera, pseudoscorpions, etc.) will become more apparent and may acquire a champion. In other words, turning trash into treasure.
All four of the processes above exist independently, but are not integrated for this particular purpose. Such a system could be created through collaboration, grants, masters or Ph.D. students, etc., but it can't be done solely at CUAC. Those interested in developing something on their own or collaborating are welcomed.
Additional samples of collection residues (although not quite as user friendly) are available from LSAM at Project 1000 Elves: www.flickr.com/photos/
