The Lymexylidae, or ship-timber beetles, are a family of wood-boring beetles, and the sole member of the superfamily Lymexyloidea. They are 5 to 40 mm long. The larvae bore into living and decaying wood (Chestnut, Poplar, and Oaks) where they eat the fungi that grow in their tunnels. Lymexylidae, a wood-boring beetle, possibly first beetles to evolve agriculture. They are fungus farmers of ''Endomyces hylecoeti'' and ''Ascoides spp.'' ==Habitat & Behavior== Symbiotic association: Fungus grows in a sheltered environment tended to by the larvae, in return, the larvae flourish and feed on the fungal farms. Wood boring activities occur primarily in the larval stage, larvae found in both sapwood and heartwood. Pestiferous: ''Lymexylon'', ''Hylecoetus'', and ''Melittomma'' to forest trees like Chestnut, Poplar, and Oaks. Some species are pests, killing live trees and damaging timber structures such as houses and ships. There are 37 species in 7 genera, including: * The ship timber beetle, ''Lymexylon navale'' * 2 species located in Eastern US and Canada include: the sapwood timberworm ''Elateroides lugubris'' (Say) * The chestnut timberworm, ''Melittomma sericeum'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lymexylidae」の詳細全文を読む スポンサード リンク
