Common Yellow Conch

<em>Agapeta hamana</em>, the common yellow conch moth, is a small moth in the family Tortricidae. It is widely distributed across Europe and central Asia, ranging from Britain and Scandinavia eastward through much of the Palearctic region. The species inhabits dry grasslands, heathlands, chalk downlands, and scrubby habitats where its larval host plants are found. Adult moths display distinctive pale yellow to golden-yellow forewings with irregular brown or reddish-brown markings near the wingtip, forming a pattern that resembles the shell of a conch, lending the species its common name. The wingspan typically measures around 15–22 mm. Biological traits such as average adult lifespan, precise body weight, and detailed population data remain poorly documented in consolidated scientific literature. Larvae feed internally on the roots of thistles and knapweeds, particularly <em>Centaurea</em> and <em>Cirsium</em> species. Adults fly from June to August and are frequently attracted to light. <em>Agapeta hamana</em> has been investigated as a potential biological control agent for invasive knapweed species in North America, where it has been introduced experimentally. The species is assessed as Least Concern given its broad distribution and stable habitat associations.

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.
