How? With womanly wiles: “Fireflies blink to attract a mate,” explains naturalist Lynn Havsall, director of programs at the George B. Dorr Museum of Natural History, in Bar Harbor, Maine. “Males fly around while females sit in trees, in shrubs, or on the ground. So find a female and watch her blinking pattern. Then imitate the pattern with a pen flashlight and the males will come to you.”

]A plus: The bugs move slowly, so they’re easy to trap in a jar. Punch some holes in the lid and add a little grass and a piece of fruit for moisture. Admire your pretty night-lights till bedtime, then let them go.
