Coreoidea

Distinguished from related superfamilies within Pentatomomorpha by combination of morphological traits: Coreidae possess leaf-like expansions on hind tibiae; Alydidae have distinctly broad, triangular heads wider than pronotum; Rhopalidae lack scent glands (hence 'scentless'); Hyocephalidae and Stenocephalidae are smaller, more cryptic groups with reduced morphological specializations. Antennae typically 4-segmented. Ocelli present. Scutellum variable in size but generally not covering entire abdomen (unlike Scutelleridae in Pentatomoidea).

Terrestrial habitats across diverse biogeographical zones; strongly associated with vegetation including tropical forests, grasslands, and agricultural areas. Many species show seasonal abundance patterns tied to monsoon and post-monsoon periods in tropical regions.

Cosmopolitan distribution with maximum species richness in the Oriental region (208 species in India alone). Major diversity hotspots include the Western Ghats and Eastern Himalayas. Well-represented in the Neotropics, Afrotropics, and Australasia. Indo-Malayan and Palaearctic regions share species indicating faunal exchange.

Peak abundance during monsoon and post-monsoon periods in tropical regions; activity patterns vary by latitude with temperate species showing spring-summer activity.

Phytophagous; feeds on plant sap, seeds, and developing fruits. Some Coreidae are specialized pod-sucking bugs on leguminous crops.

• Vigna unguiculata - pestcowpea, damaged by pod-sucking bugs including Anoplocnemis curvipes, Clavigralla spp., Riptortus dentipes, and Mirperus jaculus
• Solidago chilensis - food plantflowers fed upon by Leptoglossus species

Hemimetabolous development with egg, nymph, and adult stages. Immature stages of Hyocephalidae and Agriopocorinae described; nymphs resemble adults but lack fully developed wings and reproductive structures. Relative growth patterns of pronotum and appendage segments studied in Coreidae and Alydidae.

Some Coreidae exhibit hind leg autotomy—leaf-like tibial expansions break off easily when handled, possibly functioning as predator decoys. Antipredator defense may involve crypsis through body shape disruption.

Herbivores in terrestrial ecosystems; some species are agricultural pests of legume crops. Gut symbiont relationships with Caballeronia bacteria suggest specialized nutritional mutualisms.

Several species are significant agricultural pests, particularly pod-sucking bugs affecting cowpea and other legumes in Africa and elsewhere. Leptoglossus species feed on flowers and fruits of various plants.

• PentatomoideaBoth superfamilies in Pentatomomorpha; Pentatomoidea typically have large triangular scutellum often covering most of abdomen, and possess scent glands (absent in Rhopalidae)
• LygaeoideaClosely related and potentially paraphyletic with Coreoidea; Lygaeoidea generally smaller with more slender body form and different antennal structure
