See text Xyloryctidae is a family of moths contained within the superfamily Gelechioidea described by Edward Meyrick in 1890.

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.

This is an allusion to the caterpillar's habit of living alone in a purely residential burrow in a tree branch, to which it drags leaves at night, attaching them with silk to the entrance to the burrow and consuming the leaves as they dry out.

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.

Recent research suggests the Xyloryctidae are an independent family, sharing common ancestry with the Oecophoridae, but not descended from them.
