Clytus
clytine longhorn beetles
Clytus is a genus of longhorn beetles (Cerambycidae) in the tribe Clytini. These beetles are characterized by their wasp-mimicking coloration, typically featuring yellow and black banded patterns on the elytra. The genus is taxonomically well-established, having been described by Laicharting in 1784. Clytus species are found across the Northern Hemisphere, with records from Europe, North America, and other temperate regions.
Eupnoi
Eupnoan Harvestmen
Eupnoi is a suborder of harvestmen (order Opiliones) comprising approximately 1,700 described species across more than 200 genera. The group is divided into two superfamilies: Phalangioidea, which includes the familiar long-legged "daddy long-legs" common in northern temperate regions, and the smaller Caddoidea, characterized by prominent eyes and spiny pedipalps. Eupnoi harvestmen possess a unique secretory gland opening via an ozopore on the dorsum, which produces defensive and communicative chemicals. They exhibit complex social behaviors including multi-specific roosting aggregations and chemical-based alarm signaling.
