Bioluminescent click beetles are found throughout tropical, subtropical and temperate America. Species from Texas, Florida, Puerto Rico, and Cuba are now in different genera in the tribe Pyrophorini, such as Deilelater and Ignelater. [2] Adult Pyrophorus beetles feed on pollen and sometimes small insects, such as aphids or scale insects. Their ...
P. tenuicinctus is a medium-sized beetle, with adults that measure about 8.5–11.5 mm (0.3–0.5 in) long.The head shield, or pronotum, is pale yellow with a dark central mark that is broader at the top, slightly narrowing posteriorly and almost reaching the base of the pronotum.
[14] [15] Beetles from the family Lampyridae have been known to use certain defenses such as unpleasant odour and the excretion of a sticky substance to avoid predation. [16] Excretion of unpleasant fluids containing lucibufagins from the areas along the elytra and pronotum is the result of tactile stimulation and has been referred to as ...
Ellychnia corrusca is a medium to large beetle, with adults that are 9 to 18 mm (0.4 to 0.7 in) long. The head shield, or pronotum, has a black, rounded central mark bordered by yellow and pink on both sides.
Melanophila is a genus of buprestid beetles commonly known as fire beetles. They have extraordinary sensitivity to infrared radiation (heat), using a specialized sensor organ near their legs. [ 1 ] They seek out fires in order to mate and lay eggs in freshly burned wood.
Beetles in the genus Melanophila, such as Melanophila acuminata, are commonly known as fire beetles due to their pyrophilic habits. A pyrophile or pyrophilic / pyrophilous insect is an insect which has evolved to rely upon fire ecology for important parts of their life cycle.
These beetles are among the brightest bioluminescent insects. [1] With a brightness of around 45 millilamberts, [ 2 ] they are said to be technically bright enough to read by. [ 3 ] They achieve their luminescence by means of two light organs at the posterior corners of the prothorax , and a broad area on the underside of the first abdominal ...
Body length is about 10.5 to 15.3 mm. Head is 1.4 to 2.2 mm long with coarse moderate punctures. Maxillary palpi with apical segment moderately compressed, and cylindrical. Pronotum with strongly rounded sides and a depression along median impressed line in middle region. Pronotum punctures are moderately coarse, deep and dense.
