Colasposoma grande is a species of leaf beetle belonging to the family Chrysomelidae, specifically within the subfamily Eumolpinae. The species name "grande" is Latin for "large," indicating that it is notable for its relatively substantial size compared to many other species within its genus. Like all members of the Chrysomelidae family, it is herbivorous, feeding on the foliage of various plants.
Taxonomy
Colasposoma grande is classified within the kingdom Animalia, phylum Arthropoda, class Insecta, and order Coleoptera (beetles). Its more specific classification is as follows:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Coleoptera
- Family: Chrysomelidae (leaf beetles)
- Subfamily: Eumolpinae
- Genus: Colasposoma Laporte, 1833
- Species: Colasposoma grande (Baly, 1867)
The species was first formally described by British entomologist Joseph S. Baly in 1867.
Description
Members of the genus
Colasposoma are generally characterized by their robust, often ovate and convex bodies, and frequently exhibit iridescent or metallic coloration, which can include shades of green, blue, purple, or bronze.
Colasposoma grande shares these general characteristics but is distinguished by its larger overall body size compared to many other
Colasposoma species. While specific measurements vary, it is considered a larger representative within its genus. Like other leaf beetles, it possesses chewing mouthparts and ten-segmented antennae.
Distribution and Habitat
Colasposoma grande is primarily distributed in Southeast Asia. Its known range includes countries such as the Philippines, where it has been recorded across various islands. These beetles typically inhabit tropical and subtropical environments, including forested areas, shrublands, and often agricultural or disturbed landscapes where their host plants are abundant.
Ecology
As a phytophagous insect,
Colasposoma grande feeds on plant material. Both the adult beetles and their larvae are herbivorous. Adult beetles consume the leaves of various host plants. The larvae of Eumolpinae species, including
Colasposoma, typically live in the soil, where they feed on plant roots. The life cycle involves complete metamorphosis, progressing through egg, larval, pupal, and adult stages. Specific host plant associations for
C. grande are not broadly detailed in general literature, but they are likely polyphagous, feeding on a range of dicotyledonous plants.
