Alcathous (planthopper)

Alcathous is a genus of planthoppers belonging to the family Flatidae. These insects are primarily found in Southeast Asia and Australasia. They are characterized by their broad, often brightly colored wings that are held tent-like over their bodies when at rest.

Description

Alcathous planthoppers typically exhibit a flattened appearance. Their wings are often marked with intricate patterns and colors, serving as camouflage or potentially as a warning signal. Adults are generally small to medium in size, ranging from a few millimeters to around a centimeter in length. Nymphs often possess waxy filaments that aid in defense.

Distribution and Habitat

Species within the Alcathous genus are distributed across a range of Southeast Asian and Australasian regions, including but not limited to Australia, New Guinea, and surrounding islands. They are typically found in tropical and subtropical habitats, often inhabiting forests, woodlands, and areas with dense vegetation.

Ecology

Alcathous planthoppers are sap-sucking insects, feeding on the phloem of various plants. They insert their stylets into plant tissues to extract nutrients. While some species are relatively host-specific, others may feed on a broader range of plant species. Little is known about their specific reproductive behavior or the details of their life cycle. They are preyed upon by various insects, spiders, and birds.

Taxonomy

The genus Alcathous belongs to the family Flatidae within the order Hemiptera. The taxonomy of planthoppers can be complex, and the classification of specific species within the Alcathous genus may be subject to change as new research emerges. Further research is needed to fully understand the relationships between different species and their evolutionary history.
