Ampedus melsheimeri
(Leng, 1918)
Ampedus melsheimeri is a of click beetle ( Elateridae) described by Leng in 1918. The species belongs to a of beetles commonly associated with decaying wood and fungal substrates. Records indicate it occurs in central and eastern Canada, with scattered observations suggesting it may be uncommon or undercollected. As with many Ampedus species, detailed natural history information remains limited.

Identification
Members of Ampedus are generally recognized by their convex, somewhat cylindrical body form and often bright orange, yellow, or bicolored . Ampedus melsheimeri specifically would require examination of male genitalia or detailed comparison of pronotal and elytral proportions against such as Ampedus nigricollis or Ampedus sanguinolentus. The name honors the entomologist Frederick Ernst Melsheimer.
Habitat
Based on -level associations and Canadian distribution records, likely inhabits deciduous and mixed forests where decaying wood and bracket fungi provide larval food resources.
Distribution
Documented from Manitoba, Saskatchewan, Ontario, Quebec, and Nova Scotia, Canada. The distribution spans the Prairie Provinces through the Great Lakes region to the Maritime Provinces.
Behavior
As a click beetle, possess the ability to right themselves when overturned through a sudden flexion of the prosternal process against the mesosternum, producing an audible click. This mechanism is characteristic of the Elateridae.
Ecological Role
Larvae of Ampedus are generally saproxylic, contributing to wood decomposition and nutrient cycling in forest . They may serve as prey for woodpeckers and other .
Similar Taxa
- Ampedus nigricollisOverlapping range and similar bicolored elytral patterns; requires careful examination of pronotal shape and male genitalia for separation.
- Ampedus sanguinolentusShares reddish-orange elytral coloration; distinguished by details of pronotal punctation and elytral apices.
