Strangalia is a of longhorn beetles (Cerambycidae) first described by Audinet-Serville in 1835. in this genus are frequently observed on flowers, where feed on pollen and nectar. Several species have been documented visiting flowers of Coreopsis, Gaillardia, Ratibida, and other Asteraceae in prairie and woodland . Some species, such as Strangalia sexnotata and S. virilis, have been recorded in fermenting traps, though this attraction appears less consistent than in related genera.

Habitat
in this are associated with open woodlands, prairies, and glade . are commonly found on flowering herbaceous vegetation, particularly in areas with abundant Asteraceae. Larval is poorly documented but presumed to involve decaying wood or woody stems of plants.
Distribution
Recorded from North America, Europe (Denmark, Norway, Sweden), and the northeastern United States (Vermont). Within North America, documented from Missouri, Oklahoma, Arkansas, Texas, and Florida.
Seasonality
activity has been observed from June through September, with peak abundance coinciding with flowering of plants. Specific timing varies by and latitude.
Diet
feed on pollen and nectar of flowers. Larval diet is presumed to involve woody plant material, though specific associations remain poorly documented for most .

Behavior
are and frequently observed on flowers. Some have been attracted to fermenting traps (molasses/beer and red wine mixtures), though this is not universal across the . Strangalia sexnotata was documented from fermenting bait for the first time in a 2015 Missouri study, suggesting bait attraction may be underreported.
Ecological Role

Human Relevance
No significant economic or medical importance documented. are of interest to coleopterists and naturalists due to their flower-visiting and association with native prairie and woodland .

More Details
Fermenting bait attraction
Strangalia sexnotata was documented from fermenting traps for the first time in a 2015 Missouri study (MacRae), indicating that bait attraction in this may be more widespread than previously recognized but underreported due to limited trapping effort.
Regional endemism
Strangalia virilis is noted as a Texas/Oklahoma specialty, while S. strigosa is recorded as a Florida .
