How to Make and Use an Aspirator

An aspirator is a handy device for collecting small, delicate or active insects from under rocks or bark or for removing them from your collecting net. To use the aspirator, place the end of the tubing, indicated by"A" in the drawing, close to an insect. Then give a quick suck on the end of the tubing indicated by "B." This will draw the insect into the vial. The fine screen keeps the insect from being drawn into your mouth.

The construction of the aspirator is rather simple and needs little discussion. A spice bottle, 3 or 4 inches long, can be substituted for the vial. Each piece of tubing should be about 12 inches long, and a small piece of nylon stocking can be used for the fine screen.
