Chrysanthemum Flea Beetle

The chrysanthemum flea beetle (Psylliodes chrysocephalus) is a small leaf beetle in the family Chrysomelidae, native to Europe and western Asia. Adults are small, shiny, metallic bronze-green to blue-black beetles, and like other flea beetles, they possess enlarged hind femora that enable them to jump powerfully when disturbed, giving the group their common name. Both adults and larvae of this species feed on plants in the family Brassicaceae, particularly oilseed rape (Brassica napus), as well as members of related plant families. The specific association with chrysanthemum suggested by the common name may reflect occasional feeding on ornamental plants or historical misidentification, as the primary pest hosts in agricultural contexts are cruciferous crops. Adult beetles make characteristic small round holes in leaves, and larvae mine the stems of host plants. Psylliodes chrysocephalus is a notable agricultural pest of oilseed rape in parts of Europe, where larval stem mining can reduce crop vigor. Population levels are highest in autumn when adults are actively feeding and laying eggs. Integrated pest management strategies for flea beetle control include crop rotation, seed treatments, and biological controls.

Common Cusimanse

<em>Crossarchus obscurus</em>, commonly known as the common cusimanse or long-nosed cusimanse, is a small social mongoose in the family Herpestidae. This species is native to the rainforests and dense tropical forests of West and Central Africa. Common cusimanses are highly social animals that typically live in family groups and forage cooperatively on the forest floor, using their elongated, flexible snouts to root through leaf litter and soil in search of invertebrates, small vertebrates, and fallen fruits. They communicate through a variety of vocalizations and are known to mob and harass potential predators. The species is diurnal and terrestrial, sheltering in burrows or dense vegetation at night. Common cusimanses are assessed as Least Concern by the IUCN, with populations considered stable across their range. Biological traits such as lifespan and body measurements remain poorly documented in the scientific literature.
