Stigmella ogygia is a moth of the family Nepticulidae. This species was first described by Edward Meyrick in 1889. It is endemic to New Zealand and is found in the North, South and Stewart Islands. This species inhabits the margins of native forest where its larval plant host species are found. Eggs are laid singly on the upper side of the host plant leaf and the larva burrows directly through the bottom of the egg into the leaf-substance. The larvae mine the leaves of Senecio species including Senecio biserratus and Senecio minimus, as well as the leaves of Brachyglottis turneri. The larva emerges from its mine and pupates on the ground near of the larval host plant. Adults are day flying and have been recorded on the wing in March, July and from September to December. There are probably continuous generations throughout the year.
