Crepidodera is a of flea beetles in the Chrysomelidae, comprising approximately 40 described worldwide. Members are commonly known as Studded Flea Beetles. They belong to the tribe Alticini and possess the enlarged hind characteristic of flea beetles, enabling their distinctive jumping . The genus occurs across the Holarctic region, with species documented in North America, Europe, and Asia.

Identification
Crepidodera are among the smallest flea beetles, with often measuring 1–2 mm in length. They can be distinguished from similar small such as Chaetocnema by subtle morphological features, though definitive identification often requires examination of genitalia. The 'Studded Flea Beetles' refers to characteristic surface sculpturing. Species-level identification is challenging and typically requires knowledge.

Distribution
The has a Holarctic distribution. occur in North America (north of Mexico), throughout Europe (including Scandinavia), and extend into Asia (Turkey, Azerbaijan, Iran). GBIF records confirm presence in Denmark, Norway, and Sweden. Specific preferences vary by species; C. aurata is associated with willow, while other species occupy diverse environments.
Behavior
exhibit the jumping characteristic of Alticini flea beetles, using enlarged hind to escape disturbance. Some feed gregariously on leaf surfaces.
Similar Taxa
- ChaetocnemaBoth contain extremely small flea beetles with similar gestalt; Crepidodera may be mistaken for Chaetocnema species in the field. Chaetocnema quadricollis was historically described as having 'exactly the same aspect of a small Crepidodera.'
- NeocrepidoderaClosely related with similar and ; distinguished by systematic revisions and genetic data. Neocrepidodera transversa has been sequenced and shows comparable preferences (open, somewhat wet areas).
