Sweep nets are more rugged, and used to collect insects from grass and brush. A sweep net is swept back and forth through vegetation quickly turning the opening from ...
Small passerines are typically captured with 16-30 mm mesh, while larger birds, like hawks and ducks, are captured using mesh sizes of ~127 mm. Net dimensions can vary widely depending on the proposed use. Net height for avian mist netting is typically 1.2 - 2.6 m. Net width may vary from 3 to 18 m, although longer nets may also be used.
It visually documents insects, and unlike photography, can add intellectual ideas about anatomy and behavior of the insect through artists' renditions. Scientifically informed observation of specimens combined with technical and aesthetic skill yields the highly detailed illustrations necessary for the documentation of each species that is ...
A Malaise trap is a large, tent-like structure used for trapping, killing, and preserving flying insects, particularly Hymenoptera and Diptera. The trap is made of a material such as PET (polyester) netting and can be various colours. Insects fly into the tent wall and are funneled into a collecting vessel attached to its highest point.
The basis of any Flight Interception Trap consists of an upright placed see-through barrier under which one or more small basins are placed. The barrier may consist of such materials as plastic mesh, a transparent plastic sheet or even Plexiglas, [2] although the latter does not work well for day-active insects since it is visible to them due to its specific refraction.
