How to Make Nets

Instructions are given below for making a standard sweep net. The size and shape can be changed according to the needs of the collector, the kind of collecting to be done, and the materials available. An aerial net can be made by following the same instructions but substituting white polyester netting for the muslin.

• Fine wire or hose clamp to secure net to handle

• Handle - a large wooden dowel or discarded broom handle 30 to 40 inches long

• Muslin - 1.5 yards of material, 36 inches wide

• Sturdy wire - 4. 5-foot-long piece of wire (gauge no. 6 to no. 8) that can be bent into a rigid circle about 15 inches in diameter

• Net: Cut four muslin pieces with the dimensions shown in diagram A below.

• Sew the pieces together around the curved edges. Fold a band as shown in diagram B below and sew around the hoop.

• Hoop: Shape the hoop as indicated below, making one stem 1/2 inch longer than the other.

• Handle: On opposite sides of the handle, gouge or chisel vertical grooves for the wire stems.

• Assembly: Thread hoop into the handle grooves and fasten securely with hose clamp or with fine wires wrapped around the handle.

• Insects can be captured with a net by dragging it through vegetation or by swinging it in the air.

• Because nets are easily ripped, they should be kept away from barbed wire, briars, and thorny trees.

• Also, they should be kept dry. Moisture rots the fabric, making it tear more easily. Many insects caught in a wet net are unfit for collection.
