Continuation sheet 1
To ensure that springtails do not become stuck in the moisture underneath the sieve, arrange for a small airgap around the sieve, to allow free movement of air.
A typical setup is shown below:
2) For gathering springtails from vegetation a small close weave net can be used. Suitable nets can be obtained from Maris House Nets (tel: 01202 515 238).
Sweeping is best carried out on warm, windless days. Examine the contents of the net using a X10 magnifier and collect specimens using a pooter. The pooter mouthpiece should be fitted with a clean cotton wool filter to prevent ingestion of unpleasant organisms. Alternatively, attach a rubber bulb, from a photographic lens blower brush - squeeze the bulb in slowly and release quickly to capture the specimen(s). For live examination collect over water and use wire loop lifters (see Observation techniques). For later examination preserve in 70% alcohol with 5% glycerine.
3) For extraction of springtails from sandy soils (especially from beaches at high water mark) use a saline solution. Dissolve 2 tablespoons of salt in 1 pint (550 ml) of warm water. Allow to cool and add the soil to the water, breaking up any lumps. Springtails will rise to the surface, unharmed, and can be picked off, using a wire loop lifter (see Observation Techniques).
