Neurostrota
Ely, 1918
Neurostrota is a of small in the , established by Ely in 1918. The genus contains five described distributed in the Neotropical region and Australia. At least one species, N. gunniella, has been deployed as a agent for Mimosa pigra. are that feed internally on foliage.

Identification
Members of Neurostrota can be distinguished from related gracillariid by , particularly features of the male valvae and female sterigma. -level identification requires examination of these structures; external morphology alone is generally insufficient.
Habitat
Associated with leguminous plants, particularly Mimosa . N. gunniella occupies the upper and outer edge microhabitats of host bushes, avoiding interior foliage.
Distribution
Neotropical region ( range); to northern Australia for purposes.
Diet
Larval stage feeds as within leaves, consuming mesophyll tissue. N. gunniella is documented feeding on Mimosa pigra.
Host Associations
- Mimosa pigra - larval primary for N. gunniella; used in programs
Life Cycle
develop within leaf mines in foliage, completing development inside the leaf tissue. Specific details on , pupal, and stages are not documented in available sources.
Behavior
N. gunniella exhibits strong microhabitat selection, with preferentially mining leaves in outer positions. This pattern has been linked to higher nitrogen content and lower tannin concentrations in edge foliage.
Ecological Role
N. gunniella functions as a agent for the weed Mimosa pigra in Australia, contributing to of this .
Human Relevance
Used intentionally as a agent for Mimosa pigra, an weed in Australian wetlands and rangelands. The was to reduce vigor and spread.

More Details
Taxonomic note
The contains five described : N. brunnea, N. cupreella, N. gunniella, N. magnifica, and N. pithecolobiella. Most species were described in the 20th and early 21st centuries.
Biological control context
The microhabitat specialization of N. gunniella for outer leaves represents an that maximizes larval , as these positions offer higher quality foliage on a with variable leaf chemistry.
