Stigmella slingerlandella
(Kearfott, 1908) Wilkinson et al., 1979
Slingerland's Plum Leafminer Moth, Plum Leaf Miner
Stigmella slingerlandella is a microlepidopteran in the Nepticulidae, commonly known as the plum . The was described by Kearfott in 1908 and named in honor of Mark Vernon Slingerland. It is a leafminer on Prunus species, with larvae creating distinctive mines that begin as narrow linear tunnels before expanding into irregular blotches. The species occurs in eastern North America, where it can be a minor pest of plum and cherry .

Identification
This can be distinguished from other Stigmella by its association with Prunus plants and the specific mine : larvae initially create a narrow linear mine that subsequently widens into an irregular, more or less ovate blotch. Multiple mines (3–12) frequently occur on a single leaf. identification requires microscopic examination of genitalia; the small size (3.5–5 mm wingspan) and Nearctic distribution on Prunus help narrow possibilities. Separation from Stigmella species mining other Rosaceae depends on host plant association and detailed mine pattern analysis.
Appearance
are minute with a wingspan of 3.5–5 mm. The wings are narrow and , typical of the Nepticulidae. Coloration details of the forewings and hindwings are not explicitly documented in available sources. The body is slender and compact, adapted for the small size characteristic of pygmy moths.
Habitat
Associated with containing Prunus , including wild plum and cherry in forest edges, open woodlands, and orchards. The species occurs in temperate deciduous forest regions and agricultural settings where trees are present. Specific microhabitat preferences for are not documented.
Distribution
North America: recorded from Ontario (Canada), New York, Michigan, and Ohio (USA). The distribution possibly extends south to Florida, though this requires confirmation. GBIF records indicate additional occurrence in Vermont. The is restricted to the Nearctic region.
Seasonality
period and larval activity timing are not explicitly documented in available sources. Based on related Stigmella with similar , activity likely coincides with leaf flush on Prunus in spring and early summer.
Diet
Larvae are herbivores feeding on Prunus . Documented include Prunus nigra (Canada plum) and Prunus serotina (black cherry). Larvae mine leaves, feeding on mesophyll tissue between epidermal layers. feeding habits are unknown.
Host Associations
- Prunus nigra - larval Canada plum
- Prunus serotina - larval black cherry
Life Cycle
Holometabolous development with , larva, pupa, and stages. Larvae feed within leaf mines, initially creating narrow linear mines that widen into irregular blotches. When fully grown, larvae exit the mine through a cut in the upper leaf surface, drop to the ground, and construct a small flattened brownish cocoon in soil cracks, under loose stones, or between tree bases and surrounding soil. occurs within this cocoon. Adult timing is not specified. Multiple per year are possible but unconfirmed.
Behavior
Larvae are endophagous leafminers, feeding internally within leaf tissue. The mining progresses from an initial narrow linear phase to a broader blotch phase. Larvae exhibit negative geotaxis when mature, dropping from leaves to pupate in ground-level substrates. activity is inferred from -level traits but not directly observed. Mating and oviposition behaviors are undocumented.
Ecological Role
As a herbivore, larvae contribute to leaf damage on Prunus , though typically at low densities (3–12 mines per leaf). The species functions as a member of the native leafminer in eastern North American deciduous forests. Its role in as prey for and is likely but undocumented. No significant engineering effects are reported.
Human Relevance
Minor economic relevance as a pest of plum and cherry . Leaf mining damage is generally cosmetic rather than causing significant yield loss. The may be encountered in orchard management and is of interest to lepidopterists studying microlepidoptera. No biocontrol applications or conservation concerns are documented.
