Ambrosia Beetle
Ambrosia beetles are beetles of the weevil subfamilies Scolytinae and Platypodinae (Coleoptera, Curculionidae), which live in nutritional symbiosis with ambrosia fungi and probably with bacteria. The beetles excavate tunnels in dead trees in which they cultivate fungal gardens, their sole source of nutrition. After landing on a suitable tree, an ambrosia beetle excavates a tunnel in which it releases spores of its fungal symbiont. The fungus penetrates the plant's xylem tissue, digests it, and concentrates the nutrients on and near the surface of the beetle gallery. The majority of ambrosia beetles colonize xylem (sapwood and/or heartwood) of dying or recently dead trees. Species differ in their preference for different parts of trees, different stages of deterioration, in the shape of their tunnels (“galleries”). However, the majority of ambrosia beetles are not specialized to any taxonomic group of hosts, unlike most phytophagous organisms including the closely related bark beetles.

Famous quotes containing the words ambrosia and/or beetle:
“Someone who instinctively nourishes himself on ambrosia alone, who leaves behind what is indigestible in things.”
—Friedrich Nietzsche (1844–1900)
“Ere the bat hath flown
His cloistered flight, ere to black Hecate’s summons
The shard-born beetle with his drowsy hums
Hath rung night’s yawning peal, there shall be done
A deed of dreadful note.”
