Calendar Campaign
Since 2006, Oikos has been sharing monthly calendars as desktop wallpapers as part of a digital campaign aimed at raising awareness about nature, biodiversity, ecology, and conservation. Each year, a new theme is highlighted through 12 calendar wallpapers, offering a fresh perspective on various aspects of the natural world. Brief information about the topic is also shared along with the image on all our social media platforms and over email.
You can download the current month's calendar for standard (1280x1024), wide (1920x1080), and mobile (1080x1920) screens using the links below.

:: Wallpaper for May 2026 ::

Dear Friends,
Terastia egialealis belongs to a charming group of moths known as 'snout moths', named for their distinctive mouthparts that project forward like a tiny snout or beak, giving them an almost comical, pointed-nose look when seen up close.
This species is found across a wide sweep of Asia, from India, China, and Nepal, through Thailand and Malaysia, to the tropical islands of Sumatra, Java, Borneo, and Sulawesi.
Like all snout moths, Terastia egialealis is nocturnal, coming alive after dark. It is a striking insect, its wings and body are a warm, rusty reddish-brown, almost as if brushed with the colours of autumn.
Perhaps the most fascinating aspect of this moth is its close bond with Erythrina trees, known in India as the Pangara or Indian Coral Tree, celebrated for their brilliant red blossoms. The caterpillars feed exclusively on these trees, boring deep into their stems and shoots. This leaves a tell-tale sign, the tips of affected branches wither and die back, a quiet clue that this moth's larvae are busy at work within.
In India, this moth has been recorded in northern Maharashtra, making it a cherished part of the rich moth diversity of the Western Ghats.
Regards,
Ketaki & Manasi
With Team oikos !
