Cultus verticalis
(Banks, 1920)
Spiny Springfly
Cultus verticalis, commonly known as the spiny springfly, is a of in the Perlodidae. The species was first described by Banks in 1920 under the basionym Perla verticalis. It is known from scattered localities in eastern North America, with confirmed records from Georgia, North Carolina, New Hampshire, Pennsylvania, and Québec. As a member of the Perlodidae, it belongs to a family of predatory stoneflies commonly found in cool, well-oxygenated streams.

Identification
Identification to level requires examination of morphological characters typical of Perlodidae, including details of wing venation, genitalia structure, and body spination. The species can be distinguished from other Cultus species by the specific traits referenced in its epithet "verticalis." Specimens should be compared with type material or authoritative keys to the Cultus.
Habitat
Perlodidae stoneflies are typically associated with cool, well-oxygenated lotic (flowing water) including streams and rivers. The specific microhabitat preferences of C. verticalis are not documented, but are generally found in rocky or gravelly substrates where nymphs can hunt prey.
Distribution
Documented from eastern North America, with occurrence records from: Georgia, North Carolina, New Hampshire, Pennsylvania (USA), and Québec (Canada). The distribution appears to be disjunct across this region, suggesting potential specificity or under-sampling.
Life Cycle
As with all Plecoptera, C. verticalis has an aquatic nymphal stage and terrestrial stage. Nymphs are predatory, feeding on other aquatic . The duration of nymphal development and number of per year are not documented for this .
Ecological Role
As a predatory , nymphs function as in stream , contributing to trophic regulation of benthic . are primarily reproductive and do not feed extensively.

Taxonomic History
Originally described as Perla verticalis Banks, 1920, later transferred to the Cultus. The genus Cultus is placed in the tribe Diploperlini within the Perlodinae.
Conservation Status
Not evaluated by IUCN. The scattered distribution pattern and limited observation records (6 observations in iNaturalist as of source date) may indicate rarity or under-sampling, but no formal conservation assessment is available.
