Oedalocanthus ornatus is a of stilt bug in the Berytidae, described by Henry in 1996. It belongs to the Gampsocorinae and tribe Hoplinini. The species is characterized by its elongated, slender body form typical of stilt bugs, with notably long legs. Very few observations of this species exist in public databases, suggesting it is either rare, cryptic, or restricted to specific .

Identification
Oedalocanthus ornatus can be distinguished from other stilt bugs by its placement in the Oedalocanthus, which is characterized by specific modifications to the capsule and leg segments. Within the Hoplinini, the genus is further distinguished by features of the male genitalia and pretarsal structures. The 'ornatus' may refer to distinctive coloration or patterning that separates it from . Identification to level requires examination of these subtle morphological characters and comparison with . The species is most likely to be confused with other members of Oedalocanthus or related genera in the Gampsocorinae such as Gampsocoris or Hoplinus.
Appearance
As a member of the Berytidae (stilt bugs), O. ornatus possesses the characteristic elongated, slender body and extremely long, thin legs that give the its . The specific epithet 'ornatus' suggests some degree of ornamental or distinctive markings, though detailed morphological descriptions are not readily available in the provided sources. Stilt bugs typically have a cylindrical body form, long , and a relatively small . The Oedalocanthus is distinguished within the Hoplinini by particular features of the head and leg structure.
Habitat
Based on the -level of Berytidae and the limited distributional data, O. ornatus likely inhabits grassland, prairie, or open woodland where stilt bugs are commonly found. Members of the Gampsocorinae are often associated with herbaceous vegetation and may be found on grasses, forbs, or low shrubs. The name 'ornatus' and its description in 1996 suggest it may have been described from specimens collected in a specific, perhaps distinctive, habitat type.
Distribution
The has been documented from at least two observations according to iNaturalist data. The precise geographic range is not well-established in available sources, but the Oedalocanthus and tribe Hoplinini have distributions centered in North America, particularly in western and central regions. The description by Henry in 1996 suggests a North American type locality, likely in the United States.
Seasonality
As with most temperate heteropterans, are likely active during the warmer months, with peak activity probably occurring in late spring through summer. The specific is unknown due to limited observational data.
Behavior
Stilt bugs are generally slow-moving insects that rely on their cryptic, stick-like appearance for protection from . They are typically found on vegetation rather than flying, though they are capable of . Members of the Gampsocorinae are thought to be primarily phytophagous or , feeding on plant sap, seeds, or small . The long legs allow them to navigate through dense vegetation with a distinctive, deliberate gait.
Ecological Role
As a member of the Berytidae, O. ornatus likely contributes to nutrient cycling in grassland and open through its feeding activities. Stilt bugs may serve as prey for various including birds, spiders, and other insects. Their specific ecological role is poorly documented due to the scarcity of records for this particular .
Human Relevance
No direct human relevance has been documented for O. ornatus. The Berytidae as a contains no known significant agricultural pests or beneficial , and this rare species is unlikely to have economic importance.
