The intense coloration on the outer edges of their body gives them a painted 'border' appearance which inspired their common name. The black body has an orange-red band that separates the thorax from the abdomen. The orange wing coverings have orange edges with black speckles covering the interior. Joints on the black legs are orange. The Bordered Plant Bug can be found walking along the ground or on plants. Adults feed on the juices of soft plant tissues.

Mexican Bordered Plant Bug

Largus maculatus

Diet

  • Adults and nymphs: Primarily plant-feeding, using their piercing-sucking mouthparts to obtain sap from leaves, stems, flowers, fruits and seeds.

  • Largus species are generally associated with flowering plants and seed-producing vegetation, although the specific host plants of L. maculatus are not particularly well documented.

  • Feeding is often concentrated around developing seeds and fruits, where the insects can obtain concentrated nutrients.

  • Like other bordered plant bugs, they may also gather around fallen fruits, seeds and plant debris.

Range

  • Largus maculatus is a bordered plant bug (Largidae) in the subfamily Larginae, tribe Largini.

  • It is a New World species, occurring in Mexico and parts of Central America.

  • It is occasionally sighted in Zihua, where suitable tropical vegetation provides habitat.

Habitat

  • Found in tropical dry forest, tropical deciduous forest, scrub, grassland, forest edges, agricultural areas and disturbed vegetation.

  • Adults are commonly associated with herbaceous plants and shrubs, particularly when plants are flowering or producing seeds.

  • Around Zihua, search low vegetation, flowering plants and seed-bearing plants, especially in sunny forest margins and open scrub.

  • They may also be found on the ground beneath host plants where seeds and fallen plant material accumulate.

Size

  • Adult length: generally around 10–14 mm (0.4–0.55 in).

  • Body elongated and somewhat oval, with the characteristic appearance of a bordered plant bug.

  • L. maculatus has a distinctive black, yellow and orange colour pattern. The head and scutellum are predominantly black, while the pronotum has orange margins and the forewings are yellowish with black spotting.

  • The dark abdominal margins have c
