Things You'll Need
Instructions
Stand as still as possible in an area where you have found the dragonflies. Hold the net comfortably with one hand near the back of the handle and your dominant hand near the net.
Wait for a dragonfly to fly in front of you, across your field of vision. Do not chase dragonflies; they can change flight direction to avoid you.
Swipe at the dragonflies from behind and below as they pass in front of you. This way they do not see the net coming and are less likely to avoid it.
