picture info	Death-watch Beetle The deathwatch beetle (''Xestobium rufovillosum'') is a species of woodboring beetle that sometimes infests the structural timbers of old buildings. The adult beetle is brown and measures on average long. Eggs are laid in dark crevices in old wood inside buildings, trees, and inside tunnels left behind by previous larvae. The larvae bore into the timber, feeding for up to ten years before pupating, and later emerging from the wood as adult beetles. Timber that has been damp and is affected by fungal decay is soft enough for the larvae to chew through. They obtain nourishment by using enzymes present in their gut to digest the cellulose and hemicellulose in the wood. The larvae of deathwatch beetles weaken the structural timbers of a building by tunneling through them. Treatment with insecticides to kill the larvae is largely ineffective, and killing the adult beetles when they emerge in spring and early summer may be a better option. However, infestation by these beetles is ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Ptinidae Ptinidae is a family of beetles in the superfamily Bostrichoidea. There are at least 220 genera and 2,200 described species in Ptinidae worldwide. The family includes spider beetles and deathwatch beetles. The Ptinidae family species are hard to identify because they are so small, and they have a compact body structure. They also have similar morphologies within the genera and species of the family. There are three main groups in the superfamily Bostrichoidea: Bostrichidae, Anobiidae, and Ptinidae. These have undergone frequent changes in hierarchical classification since their inception. They have been treated as a single family, three independent families, the two families Bostrichidae and Anobiidae, or the two families Bostrichidae and Ptinidae. More recent literature treats these as the two families Bostrichidae and Ptinidae, with Anobiidae a subfamily of Ptinidae (Anobiinae). Spider beetles are so named because they look like spiders. Some species have long legs, antenna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

	Bostrichoidea Bostrichoidea is a superfamily of beetles. It is the type superfamily of the infraorder Bostrichiformia. Description The Bostrichoidea are united by the following features: modified cryptonephridism, the structure of the aedeagus in males, and the lack of a basal mandibular mola in larvae. Aside from this, Bostrichoidea show a range of morphologies. For example, in Bostrichidae alone, the adult body shape varies from convex to flattened, the body length from 2 to 50 mm, and the colour may be yellow, brown or black and sometimes has a metallic hue. Ecology Bostrichoids generally live in dry habitats. For example, many Bostrichidae feed on wood, though some attack monocotyledonous plants as well and ''Rhyzopertha dominica'' feeds on stored grains and cereal products. Similarly, most Ptinidae are wood-borers as larvae but some feed on other dry plant or animal material, such as stored foods, tobacco and museum specimens. Dermestidae are typically scavengers on dried organic m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
