Xyloryctidae is a family of moths in the superfamily Gelechioidea. Most geera are found in the Indo-Australian region. While many of these moths are tiny, some members of the family grow to a wingspan of up to 66 mm, making them giants among the micromoths.
The name ‘timber moths’ was coined by the Queensland naturalist Rowland Illidge in 1892, later published in 1895, and serves to distinguish these moths from other wood-boring Australian moths such as ghost moths Hepialidae and giant wood moths (Cossidae), which feed on sap or wood. It refers to the fact that the larvae of most members of this family are arboreal, whether they burrow into branches, bore into flower heads, tunnel under bark, or feed on lichens. Moths of the genus Maroga are pests of wattles (Acacia) and have crossed over from their wild host plant to become serious pests of cultivated stone fruit trees, particularly cherries.
Formerly, Xyloryctidae were placed in the Oecophoridae as the subfamily Xyloryctinae. Recent research suggests the Xyloryctidae are an independent family, sharing common ancestry with the Oecophoridae, but not descended from them.
