Fireflies Make Grand Appearance in Greeley

There is a reason we don't see fireflies very often these days. However, they are out and about in Greeley and this Thursday is a rare night walk to see them.
Fireflies in general are becoming harder and harder to see worldwide. Many scientists think it largely due to light pollution and development. There are actually over 2000 different species of fireflies and they are all becoming more rare every year. Many areas like Northern Colorado may only see them every 3-5 years, if that.

Both male and female fireflies use their flashing lights to communicate. Some species synchronize their flashes, sometimes across large groups of thousands of insects. All species speak a language of light—scientists believe they use it to attract mates, defend their territory, and warn off predators.

Sure, you may see a firefly here and there but not in large groups. Chris Sully, a City of Greeley parks maintenance technician, says there are out in force along the Sheep Draw Trail. The area is classified as "open space" so the area is normally closed at night, but this Thursday, the city will be hosting a special night walk.

The free event will be this Thursday, July 2 starting at 9:00 p.m. in the McCloskey Open Space area along the Sheep Draw Trail. If you would like to come out, please meet at the amphitheater on the east side of the Family FunPlex located at 1501 65th Avenue in Greeley. Just make sure you wear good shoes as the walk will take about an hour and bring your own water, bug spray and you're welcome to bring glow sticks as well.
