clay triple-lines

The Clay Triple-lines, Cyclophora linearia, is a geometrid moth in the family Geometridae found across Europe and temperate Asia, inhabiting deciduous woodland, hedgerows, and scrubby areas where its larval host plant beech (Fagus sylvatica) is present. The forewings are pale clay-buff to cream, crossed by three distinct darker brown or ochreous lines from which the common name derives, with a small darker discal spot. The hindwings are similarly patterned but slightly paler. The species is well camouflaged at rest on bark and dead wood. Adults are crepuscular and nocturnal, flying in two generations per year in much of its range, with adults on the wing in spring and again in summer. The larvae feed on the young leaves of beech trees, and the species is strongly associated with mature beech woodland throughout its range. As beech woodland becomes increasingly threatened by climate change, drought stress, and changing forest management practices across Europe, specialist beech-associated insects like the Clay Triple-lines may face habitat contractions. The species is currently widespread and not considered globally threatened, but national populations show variation in abundance tied to the health of beech forest habitats.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
