Nemognatha nitidula
Enns, 1956
blister beetle
Nemognatha nitidula is a of blister beetle in the Meloidae, described by Enns in 1956. It belongs to the Nemognathinae, a group characterized by elongated maxillary mouthparts adapted for nectar feeding on flowers. The species is found in North America and is part of a known for its distinctive floral associations and capillary-based nectar uptake rather than true sucking mouthparts.

Identification
Nemognatha nitidula can be distinguished from other Nemognatha by features described in Enns' 1956 revision of North American Nemognatha, Zonitis, and Pseudozonitis. Members of Nemognathinae are recognizable by their elongated, bristle-covered maxillary that function in nectar feeding. The specific distinguishing characters for N. nitidula would include details of body proportions, coloration, and mouthpart structure relative to congeneric species, though these require examination of the original description.
Distribution
North America. The is recorded from North America based on museum holdings and distribution data, with specific locality records requiring further documentation.
Diet
feed on nectar from flowers, using elongated maxillary covered in bristles that transport nectar via capillary action rather than suction. The larvae are likely or , as is typical for Nemognathinae, though specific records for N. nitidula are not documented.
Behavior
are flower visitors, utilizing their specialized elongated mouthparts to access nectar in flowers with deep corollas. The feeding mechanism involves capillary action along bristle-covered rather than true sucking.
Ecological Role
As , contributes to pollination through flower visitation. Larval stages likely function as or in soil or nests, though specific ecological impacts are undocumented for this .
Human Relevance
Like other blister beetles, may contain , a defensive compound with potential . Not a significant agricultural pest based on available records.
