	Flat Grain Beetle ''Cryptolestes pusillus'' is a species of lined flat bark beetle native to Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia .... It is also known as the flat grain beetle. It feeds on grain products, and is considered a pest in Canada.

	Foreign Grain Beetle The foreign grain beetle (''Ahasverus advena'') is a species of beetle in the family Silvanidae. It is related to the sawtoothed grain beetle. Description The foreign grain beetle is approximately 2 mm ( in) in length. It can be distinguished from other grain beetles from its slight projections or knobs on each front corner of the pronotum, and its club-shaped antennae. However, other '' Ahasverus'' species look very similar and particular confusion can occur with '' Ahasverus rectus'', which is also found in grain bins in North America. The larvae are worm-like, cream-colored and often reach a length of 3 mm before pupating into darker adults. Males and females are identical in appearance both as larvae and adults. The adult is usually reddish brown, or sometimes black. Natural history Distribution The foreign grain beetle is found in tropical and temperate regions. It can complete development at temperatures between 20 and 35 °C. Behavior At 30&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Oryzaephilus Mercator ''Oryzaephilus mercator'', the merchant grain beetle, is a small, flattened beetle about 2.5mm in length. It is a common, worldwide pest of grain and grain products as well as fruit, chocolate, drugs, and tobacco. The biology of ''O. mercator'' is nearly identical with ''Oryzaephilus surinamensis'' (the sawtooth grain beetle). It can be differentiated from ''O. surinamensis'' by its larger eyes and by the shape of the head, the area just behind the eyes of ''O. mercator'' is narrower than that of ''O. surinamensis'', which has a more triangular shaped head. Unlike ''O. surinamensis'', adults are capable of flight. Life cycle Females produce from 500 to 1000 eggs in a year which are deposited within a food source. The larvae are yellowish-white with a brown head and can reach a length of up to 3mm, larvae are active and move about through a food source as they feed. Larvae molt In biology, moulting (British English), or molting (American English), also known as sloughing, sheddi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Saw-toothed Grain Beetle ''Oryzaephilus surinamensis'', the sawtoothed grain beetle, is a beetle in the superfamily ''Cucujoidea''. It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco. The species's binomial name, meaning "rice-lover from Suriname," was coined by Carl Linnaeus, who received specimens of the beetle from Surinam. It is also known as the malt beetle and may be referenced in the poem This Is The House That Jack Built in the line "....the rat that ate the malt that lay in the house that Jack built" the malt referenced may not be actual malted grain but a sawtoothed grain beetle. Description and Identification ''O. surinamensis'' is a slender, dark brown beetle 2.4–3 mm in size, with characteristic "teeth" running down the side of the prothorax. It is nearly identical to ''Oryzaephilus mercator'', or the Merchant Grain Beetle, however, ''O. surinamensis'' has smaller eyes and a broader, more triangular head; ''O. surinamensis'' unlike ''O. ...

	Flour Beetle Flour beetles are members of the darkling beetle genus, genera ''Tribolium (beetle), Tribolium'' or ''Tenebrio''. They are pests of cereal silos and are widely used as laboratory animals, as they are easy to keep. The flour beetles consume wheat and other grains, are adapted to survive in very dry environments, and can withstand even higher amounts of radiation than cockroaches. They are a major pest in the agricultural industry and are highly resistant to insecticides. The larvae of ''T. molitor'', when full-grown, are known as mealworms; small specimens and the larvae of the other species are called mini mealworms. Flour beetles are part of the life cycle of the tapeworm ''Hymenolepis nana'', which causes hymenolepiasis in humans. Female reproduction is distributed over their adult life-span which lasts about a year. Flour beetles also display pre-mating discrimination among potential mates. Female flour beetles, specifically of ''T. castaneum'', can mate with different males a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
