IMAGING FLUID-STORED ARTHROPOD COLLECTIONS USING 3D PRINT TECHNOLOGY
Natural history museums have progressed considerably in digitally imaging the holdings of pinned material, however imaging of fluid preserved collections still lags. Imaging specimens in ethanol requires handling numerous specimen per museum record and managing issues related to lighting and reflective surfaces. To speed up the handling process and reduce challenges with imaging in ethanol, we designed a polylactic acid imaging box using 3D print technology designed around readily-available, optically-clear microscopy supplies. We designed a process for operators to work in teams to scan collections in batches using a flatbed scanner. To batch crop images and standardize the size of images, we wrote functions in R. At 2400 dpi, resolvable structures for adult Trichoptera included segments of antennae, individual setae on the head and abdomen, shape of maxillary and labial palp segments, shape and count of tibial spurs, wing detail, and some detail on male genetalic structures. This low-cost and standardized imaging box model is available for download and can be used for imaging museum material, image vouchering for DNA, recording body size information for ecological samples, or in recordkeeping step for biomonitoring samples.
