16-5-2023 KOTA KINABALU NAT PRK, BORNEO - GEOMETER MOTH (Ourapteryx picticaudata)


The GEOMETER MOTH (Ourapteryx picticaudata) is a specific species of geometer moth belonging to the diverse family Geometridae. Native primarily to the Southeast Asian regions of Borneo, Peninsular Malaysia, and Sumatra, this species is typically found in higher-altitude, mountainous environments.

Key Characteristics & Facts

Geographical Range: Endemic to tropical regions in Southeast Asia.

Family Roots: Like all geometer moths, the larvae are famously known as "inchworms" because of the looping, earth-measuring way they crawl.


Physical Appearance: They belong to the genus Ourapteryx, members of which are often characterized by their bright white to pale yellow, butterfly-like wings, distinctive pointed tails (similar to the European Swallow-tailed moth), and delicate transverse bands across the wing surfaces.

Family Traits: The broader Geometridae family is one of the largest in the Lepidoptera order, boasting over 23,000 described species. While specific wingspan and lifespan data for Ourapteryx picticaudata are not broadly separated from the family averages, the wider family features wingspans from 10 mm to 70 mm and an adult lifespan typically ranging from 5 to 9 days.
