Perhaps the best known species is Zophobas morio, synonymously known as Zophobas atratus, a beetle whose larvae are robust mealworms sold as food for pets [4] such as lizards. The larvae are known commonly as "superworms". [5] Superworms should not be confused with darkling beetle mealworms sprayed with juvenile hormone. [6]
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815.
The larvae resemble very large mealworms, about 50 to 60 mm (1.7–2.25 in) long when full size, but unlike mealworms, the ends of their bodies are very dark, almost resembling a black color. Once they reach sufficient maturity, the larvae pupate, emerging with a white to light brown colour; eventually darkening to black. The larvae fail to ...
Darkling beetle is the common name for members of the beetle family Tenebrionidae, comprising over 20,000 species in a cosmopolitan distribution. Taxonomy [ edit ]
When a click beetle bends its body, the peg snaps into the cavity, causing the beetle's body to straighten so suddenly that it jumps into the air. [ 5 ] Most beetles capable of bioluminescence are in the Elateroidea, in the families Lampyridae (~2000 species), Phengodidae (~200 species), Rhagophthalmidae (100 species) and Elateridae (>100 species).
The larvae of the litter beetle, like certain other larvae of darkling beetles such as mealworms, are used as animal feed, e.g., fed to captive reptiles. [ 16 ] [ 17 ] [ 18 ] They have been reported as a good first food for Central American wood turtle ( Rhinoclemmys pulcherrima mannii ) hatchlings, because they are more active than common ...
Some elateriform larvae of click beetles are known as wireworms. Beetles in the Scarabaeoidea have short, thick larvae described as scarabaeiform, more commonly known as grubs. [89] All beetle larvae go through several instars, which are the developmental stages between each moult. In many species, the larvae simply increase in size with each ...
Larvae are elongate, cylindrical and reddish-brown. They are notable for the shape of the ninth abdominal segment, which is obliquely truncate (ending abruptly). The truncate surface is strongly concave and has acute margins. This is unique among larvae of North American darkling beetles. [5] Pupae are about 15 mm long. They are mostly cream ...
