Chlorochroa opuntiae
Esselbaugh, 1948
Chlorochroa opuntiae is a of in the Pentatomidae, first described by Esselbaugh in 1948. It belongs to a of green-colored stink bugs found in North America. The species name 'opuntiae' suggests an association with Opuntia (prickly pear cactus), though specific ecological relationships require further documentation. It occurs in the western Nearctic region, with records from California and surrounding areas.

Identification
Identification to level within Chlorochroa requires examination of subtle morphological characters, particularly male genitalia and pronotal structure. C. opuntiae can be distinguished from the more widespread C. sayi and C. ligata by specific features detailed in Esselbaugh's 1948 original description. Field identification is challenging without microscopic examination; dissection and comparison with type material or expert determination is typically required for confident identification.

Appearance
are medium-sized stink bugs with the characteristic shield-shaped body typical of Pentatomidae. Members of the Chlorochroa are generally green in coloration. Specific diagnostic features distinguishing C. opuntiae from include subtle morphological differences in the pronotum and genitalia as described in the original description. Like other Chlorochroa species, it likely possesses the typical pentatomid body plan with a large triangular scutellum covering much of the .
Habitat
Specific preferences are poorly documented. Based on the epithet and distribution, it likely occurs in arid and semi-arid regions of western North America where Opuntia cacti are present. Like other Chlorochroa species, it probably inhabits a variety of herbaceous and woody vegetation in these environments.
Distribution
Western Nearctic region of North America. Documented from California and surrounding areas. The GBIF distribution record indicates presence in North America, specifically the Western Nearctic excluding Beringia, with California as a documented location.
Seasonality
activity period is not well documented. Based on related in the , activity likely occurs during the warmer months, approximately May through September, though specific phenological data for this species are lacking.
Host Associations
- Opuntia - possibleThe epithet 'opuntiae' suggests a potential association with prickly pear cactus (Opuntia), though this relationship has not been formally documented in the available literature.
Ecological Role
As a phytophagous , likely functions as a herbivore feeding on plant sap, potentially with some role in nutrient cycling. Specific ecological impacts are unknown due to limited study.
Human Relevance
Not known to be a significant agricultural pest. Unlike some such as C. ligata, no documented economic damage to crops has been reported. The appears to be of minimal direct concern to agriculture or human welfare.
Similar Taxa
- Chlorochroa sayiSimilar green coloration and general body form; requires examination of male genitalia and pronotal characters for separation.
- Chlorochroa ligataOverlapping distribution and similar appearance; C. ligata is a known pest of multiple crops and can be distinguished by specific morphological features detailed in taxonomic keys.
- Chlorochroa granulosaAnother western Nearctic with green coloration; -level identification requires careful morphological comparison.

Taxonomic History
Described by Esselbaugh in 1948, this has received limited subsequent taxonomic attention. The Chlorochroa is in need of modern revision, and species boundaries may benefit from additional study incorporating molecular data.
Research Needs
Basic biological information including plant associations, , and ecological requirements remain undocumented. The suggested association with Opuntia indicated by the epithet warrants investigation.
