Collecting, preparing, and preserving insects, mites, and spiders /

The differences in design consist of modifications of some or all of the three main parts of the net: the ring, the bag, and the handle. [...] When you catch a large insect or a specimen of Lepidoptera in your net, twist the handle quickly and lap the bag over the ring, enclosing the specimen in the bottom of the bag. [...] To remove the insect from the net, grasp the bag and enclose the specimen in a small fold of the cloth. [...] Inside the inner chamber and just below the lower end of the funnel is a small container with a screen lid, the rain drain (c), which has a tube leading from it down through the bottom of the outside of the trap; the container catches and drains off any water that enters through the funnel. [...] The heating element is separated from the pad containing the tetrachloroethane only by the thickness of the metal forming the bottom of the reception chamber.
