Photinus macdermotti, or Father Mac's firefly[2] or Mr. Mac,[3] is a species of firefly in the family Lampyridae.[2][4] It is found in North America.[4]
Description
[edit]P. macdermotti is a medium-sized beetle, with adults that measure about 10 mm (0.4 in) long. The head shield, or pronotum, is pale yellow with a black, rectangular central mark bounded by red or pink. The wing covers, or elytra, are dark with well-defined, light-colored margins. The male has lanterns in segments 6 and 7 of its abdomen, and the female has only one lantern. It is nearly identical in appearance to Photinus consanguineus and Photinus greeni.[3]
Etymology
[edit]Photinus is from the Greek word for shining or bright.[5] The species honors Frank McDermott, a firefly expert from the 1900s.[3]
Life Cycle
[edit]Beetles such as P. macdermotti go through four life stages: egg, larva, pupa, and adult. Photinus fireflies spend the majority of their lives as larvae, which are bioluminescent and likely live below the soil surface, eating snails, worms, and other soft-bodied invertebrates.[1][3]
Behavior
[edit]Adult male P. macdermotti fireflies fly 0.3–1.2 m (1–4 ft) off the ground and flash to attract the attention of females. Their flash pattern consists of two quick pulses of light, with each pulse approximately 0.25 seconds in length, with a period of 2 seconds of darkness before the next set of 2 pulses at 70 °F (21.1 °C). A female responds with an answering flash from a perch on low vegetation. The male and female communicate in this way until the male finds the female and they mate.[3]
Habitat
[edit]These fireflies can be found in both lower-elevation forests and higher-elevation river valleys and open forests.[3]
Range
[edit]P. macdermotti is found in the eastern United States from Oklahoma to the west, Florida to the south, and New England to the north. It is also found in Ontario, Canada.[1]
