It also has to be recognised that for some species netting and observation in the hand is required for positive identification. This is especially true for female damselflies and we have indicated in the species pages where particular problems can arise. Types of nets There are many types of net available and what you end up using will be determined by personal choice. Heavy duty pond and sweep nets are not suitable. What is needed is a insect net with a lightweight nylon bag and an aluminium handle.
Nets can be either black or white.
Some species are reported to detect and avoid white nets, so black is often recommended, but technique is probably as important for success. The frame can be round or kite-shaped. A large opening is an advantage for catching larger species, but this has to be balanced against portability and manoeuvrability. A long and preferably extendable handle is needed. We personally use circular nets with a diameter of about 30cm, with a deep black nylon bag.
