With firefly season drawing ever closer, we thought it would be a good time to share some tips for making your yard friendlier to these bright bugs. In addition to a wealth of information on fireflies, Silent Sparks by Sara Lewis includes a handy field guide for the firefly-enthusiast. Use these to fill your yard with twinkling lights during the summer evenings ahead.
Fireflies love a yard with spots of longer grass because when grass is longer, the soil holds more moisture. Fireflies need moist places to lay their eggs. If you leave some leaf litter and other natural debris in your yard, baby fireflies will have a place to grow.
When thinking about outdoor light, err on the side of less. Light pollution confuses fireflies during their courtship rituals. Use Dark-Sky compliant, shielded fixtures. Use bulbs with the lowest wattage that will meet your needs. Turn off outdoor lights when you’re not using them, or put them on timers or motion sensors.
Finally, limit your use of pesticides to horticultural oils or insecticidal bacteria that will target specific pests. Consider using organic products, and only apply them to target specific problems as opposed to routinely.
If you follow this expert advice, you’ll be on your way to a sparkling summer! While you’re at it, enter to win your own copy of Silent Sparks.
