We had a nice, raucous crowd tonight with 7 guests! Our group was excited about outdoor adventures that had been accomplished, as well as eager with anticipation of future events. We did not scare off the guests, though, so the night was a success even before our speaker shared tales of fireflies.
Ben Pfeiffer is the creator of www.firefly.org, a non-profit project all about fireflies. He presented fascinating information about the life cycle and the history of the little beetles who shine in the darkness of night, offering a friendly glow to the weary eye at the end of the day. It seems that fireflies are believed to have originated 125-150 million years ago and are in every continent except Antarctica. The flashing lights of the little friends are mostly a way to attract mates.
There are 2,000 species of fireflies worldwide, 200 in the United States, and 40 in Texas. Georgia and Florida have the highest concentrations. Fireflies are easily adaptable but one can help maintain a good, welcoming environment by eliminating pesticides, tilling the soil, and adding enrichment to the soil (such as compost). It also helps to try and maintain dark skies as much as possible.
Each species has its own pattern of flashing and color. The bioluminescence is the oxidation of luciferin in the abdominal segments of the beetle. The firefly larvae eats snails, slugs, dead insects, and worms, as well as their own. The most common firefly in this Texas region is Photinus Pyralis.
Ben was gracious enough to offer help on identifying a firefly if you cannot determine the type. He may be contacted at . Additional resources include www.texasento.net and www.bugguide.net.
The night ended with a smile as TOWNies left with eyes upward, looking for the little lights of the night as we walked back to our cars. It is nice to know that the lights continue to shine even after the dark night settles in.
Happy Trails,
