Best way to catch insects?

Question

I need to catch and pin at least 25 insects (from different orders) for my biology project. What's the easiest, cheapest, and most efficient way for me to catch insects at home without damaging them? (I need them as whole as possiblE)

Answer 1

This method takes two people:  Find an open field that does not have a big ditch.  Hopefully, the grass will be nearly window high.

Get your passenger to hold the net out the passenger window.  The driver makes passes from one side of the field to another as many times as you need to catch the quota.

Repeat in as many fields as required.

It worked for Jimmy and me when  he had to get 150 bugs.
