-Genus Loxa​


Loxa is a genus of stink bugs in the family Pentatomidae, commonly recognized for their bright green, shield-shaped bodies and strong defensive odor. These bugs have a broad, somewhat triangular form with a large central plate (the scutellum) and well-developed wings, giving them the classic “shield bug” appearance. Species of Loxa are typically plant feeders, using a piercing-sucking rostrum to extract juices from leaves, stems, fruits, and seeds. Their coloration helps them blend into foliage, making them less visible to predators. When disturbed, they release a characteristic odor from scent glands, which acts as a chemical defense.

Loxa Stink Bugs

Loxa (Genus)

Diet

  • Adults and nymphs: Primarily plant-feeding, using their piercing-sucking mouthparts to feed on plant sap, developing fruits, flowers and seeds.

  • Species of Loxa are generally associated with woody plants and flowering vegetation, although host-plant information varies considerably among species.

  • Feeding on developing fruits and seeds can cause blemishes, deformation and reduced plant or crop quality.

Range

  • Loxa is a genus of stink bugs (Pentatomidae) in the subfamily Pentatominae.

  • The genus is primarily Neotropical, occurring from Mexico and Central America through the Caribbean and into South America.

  • They are occasionally sighted in Zihua, where tropical vegetation provides suitable habitat.

Habitat

  • Found in tropical dry forest, tropical deciduous forest, woodland, scrub, forest edges, gardens and agricultural areas.

  • Adults are generally encountered on trees and shrubs, particularly where flowering, fruiting or seed-producing plants provide suitable food.

  • Around Zihua, search carefully on foliage, flowers and developing fruits, especially in forest edges and sunny areas.

  • Their green colouration can make them surprisingly difficult to detect against leaves.

Size

  • Adult Loxa are generally medium to large stink bugs, commonly around 15–20 mm long, depending on species.

  • The body is broadly shield-shaped, with a large triangular scutellum and five-segmented antennae typical of Pentatomidae.

  • Many species are predominantly green, although yellow, brown and other colour variations occur.
