The best tools to have in a lab are a stereoscope, petri dishes,
and forceps.
A stereoscope (Figure a.) is necessary because it
provides depth perception, a good light source, and an acceptable
magnification. Do not use standard light microscopes as they have
too high of a magnification (all you will see is a dark blob). The
scope photographed has a magnification level from x8 to x32, meaning
whatever you look at is magnified by 8 to 32 times.
Place the insect in a petridish. Make sure the dish is filled with
water. If the insect is moving too fast in the dish, place the insect
in a refrigerator until it slows down. This generally takes from one
to twelve hours.
When observing the insect, you can use a pair of forceps to carefully
manipulate the insect. Just be careful, remember that insects are
extremely fragile and are easy to crush.
If you want to make a collection of insects, the easiest and most
versatile way (and takes up the least amount of space) is to take
digital photographs. You will want to use a camera that is at least
2 to 3 megapixals and and has an optical zoom of at least x10 (for
the small insects). If an insect of only a few millimeters is photographed,
an optical zoom of x17 will be required. Keep the insect in the petri
dish, and place the dish on piece of black construction paper. The
insect will most likely have to refrigerated as above. The pictures
that I took outside turned out the best.
