The entire bag of the net is generally constructed from a lightweight mesh to minimize damage to delicate butterfly wings. Other types of nets used in insect collecting include beat nets ...
The bag of a butterfly net is generally constructed from a lightweight mesh to minimize damage to delicate butterfly wings. 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 side to side and following a shallow figure eight pattern.
The town is known for the butterfly fishermen who are skilled at lowering their butterfly-shaped nets to catch "pescado blanco" (Chirostoma estor), [4] a species of freshwater silverside endemic to the lake which is important to the local cuisine.

Once even a small portion is bitten off, that fruit ...
The net is first oriented longitudinally in hot water and then transversally in a ramose. The final result is a net with a lot of tensile strength (between 50 and 70 kg per meter) that weighs between 6 and 9 grams per square meter, and a mesh size that may reach up to 30x30 cm according to the technical capacity of the manufacturer.
