Gnorimella maculosa

The combination of spotted elytral patterning, moderate size (~15 mm), and association with eastern North American deciduous woodlands distinguishes this species from similar cetoniine scarabs. It is the only species in the genus Gnorimella, which may be distinguished from related genera (e.g., Trichius) by subtle morphological characters of the scutellum and elytral suture, though precise diagnostic features are not detailed in available sources.

Approximately 15.2 mm in length. Elytra bear distinct spotted (maculate) patterning. Body form typical of flower chafers (Cetoniinae), with somewhat rounded, convex profile.

Deciduous woodland and adjacent edge habitats. Specific microhabitat preferences (e.g., canopy level, ground stratum) are not documented in available sources.

Eastern North America: Canada (New Brunswick, Nova Scotia, Ontario, Quebec) and United States (Alabama, Connecticut, District of Columbia, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Virginia, West Virginia, Wisconsin).

Occasionally encountered by entomologists and naturalists; 283 observations recorded on iNaturalist as of source date. No documented economic or agricultural significance.

• Trichius speciesOther eastern North American flower chafers share similar size and general body form, but differ in elytral pattern (often banded rather than spotted) and lack the specific maculate pattern of Gnorimella maculosa
• Other Cetoniinae generaGeneric placement requires examination of detailed morphological characters; Gnorimella is distinguished as monotypic genus
