Description |
Adults are soft-bodied, elongated, and flattened. Most are brown or black with light markings. They have nearly parallel sides and rounded ends. The exoskeletal plate covering the thorax (pronotum) is nearly as wide at the base as the forewings (elytra). The front of the pronotum is extended forward and completely covers the head, though the head may be extended beyond it. The elytra are leathery and loosely cover the body. The last 2 or 3 abdominal segments are often luminescent. The last part of the leg (tarsus), corresponding to the foot, has 5 segments. |

Found a firefly on the bottom of a zucchini that was growing in my straw bale garden. It was probably trying to get some shade & stay cool on this hot, muggy day. |

Watch: Fireflies Glowing in Sync to Attract Mates | National Geographic |
About
Sep 4, 2016 Each year in late spring the Great Smoky Mountains National Park hosts a special light show, thanks to a species of beetle native to the region. These are the synchronous fireflies, known for coordinating their flashes into bursts that ripple through a group of the insects. As with other fireflies, their yellowish glow helps potential mates find one another. |
