Description: This is in no way original, but I want to record use of alcohol hand gel as a temporary mounting method for springtails. Alcohol hand gel is readily available in supermarkets and chemists. There are many different brands but choose a colourless one containing 70% alcohol (which although not stated, I think is isopropanol?). You probably won't be able to find a brand without perfume, so you're going to smell nice (?) after using it! Buy the cheapest you can find (always a guiding principle). The full list of ingredients of the one I use is: alcohol (isopropanol?), water, glycerin, acrylates/alkyl acrylate crosspolymer, perfume, triethanolamine, aloe barbadensis extract, phenoxyethanol. There's a lot of other stuff in there in addition to the alcohol, but the extra gloop turns out to be useful. Put a springtail (or other small insect) on a clean microscope slide and put a drop of the gel on top, then a coverslip. The gel and the coverslip allows you to roll the specimen around to see the features you want - an advantage of the gel consistency. I am able to get very good resolution of specimens mounted in this way, including being able to resolve manubrial teeth and macrosetate insertion points, something I have not been able to resolve using other methods. I have also taken specimens from the gel and then cleared them or put them back into 70% alcohol for storage without any problems, so I would definitely recommend a bottle of hand gel in your springtail kit.

Description: In spite of all the rain and good numbers of springtails over the last few weeks (dominated by Dicyrtomina saundersi), Isotomids have been largely missing. However, the recent haul of leaf litter had good number of Isotoma viridis, a species I have not seen since last winter. Date: 10 November 2019, 14:38. Source: Isotoma viridis. Author: AJC1.
