2013 entomology collections – some highlights posted

Here are – all posted with kind permission – some photos of the student collections submitted as part of this year’s General Entomology course. The collections shown were among the most diverse, and/or well presented final submissions (however the line-up is far from complete). Students had to accumulate 100 insect specimens, curate them properly, and identify each specimen to the level of family.  Congratulations!

Hasbrouck Insect Collection reaches 40,000 on-line records

Last week the ASUHIC’s on-line holdings reached the number of 40,000 specimen records – 100% georeferenced – and representing > 80 families, 860 genera, and 2600 species. Prioritized families include Crabronidae, Curculionidae, Formicidae, Mutillidae, and Scarabaeidae all with > 4000 records. We also have ~ 730 high-resolution images on-line. Thanks to our undergraduate students – current and past – for your quality work.

Article digest: rotational scanning electron micrographs

Two recent papers by Akkari et al. and Cheung et al. describe and showcase a cool method of creating 3D rotational SEM images (see “Articles” below).

In this method, the authors mounted insect and millipede samples on a rotating platform inside a SEM machine and took a series of snapshots at an incremental angle. Then these snapshots were put together to create 3D flash images using Adobe Flash. The 3D flash images can be embedded in a PDF, allowing readers to access the 3-dimensional structural details of a sample.
