A guide to finding mini-beasts
A sweep net is a long net with a wide opening used to catch flying insects or in a grassland environment.
A specific insect, such as a butterfly, could be targeted and caught in order to be identified. Or successive sweeps could be carried out on a section of grassland, capturing anything resting on the grass- often including invertebrates such as beetles, bugs, grasshoppers and spiders.
The top of the net should be closed quickly after each sweep, with a flick of the wrist, to prevent the catch escaping. Care should be taken not to sweep in areas with branches or spiky vegetation, as the net will get caught.
