Blocky Fungus Weevil

Homoeodera rotundipennis

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Homoeodera rotundipennis faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to forest fragmentation, while its small population size increases extinction risk from stochastic events. Climate change poses an additional threat by altering the microhabitat conditions essential for this beetle's survival.

Threat summary

Habitat

This critically endangered beetle inhabits specialized microhabitats within tropical and subtropical forests, typically associated with specific host plants or decaying organic matter. The species requires intact forest ecosystems with stable moisture and temperature conditions.
