Parectopa leucocyma
Parectopa leucocyma, also known as the kauri leafminer, is a species of moth in the family Gracillariidae. It is endemic to New Zealand. Taxonomy. This species was described by Edward Meyrick in 1889 using a specimen he collected in the Waitakere Range in Auckland and named "Gracilaria leucocyma". George Hudson discussed this species under the name "Parectopa laucocyma" in his 1928 publication "The Butterflies and Moths of New Zealand." The specimen collected by Meyrick was the only recorded specimen until this species was rediscovered in 1954 by K. A. J. Wise. In 1961 Lajos Vári restricted the genus  Parectopa to Holarctic species which do not have genital characteristics that resemble New Zealand species. As a result, John S. Dugdale placed this species in the genus "Acrocercops". However the genus level classification of "Acrocercops leucocyma" is regarded as unsatisfactory and as such the species is currently also known as "Acrocercops" ("s.l.") "leucocyma." The holotype specimen is held at the Natural History Museum, London. Description. Meyrick described this species as follows: Distribution. This species is endemic to New Zealand. Biology and life cycle. The adult moths of this species are on the wing in December. Habitat and host species. The  larvae feed on "Agathis australis". They mine the leaves of their host plant. The mine starts at the tip of the leaf and then heads for the general direction of the petiole, sometimes double-backing along the way. Near the petiole, the host plant forms a gall, creating a sheltered site for the larva to overwinter. After hibernation, the larva chews itself out of the gall and pupates on the leaf in a parchment-like cocoon.
