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.

Dear Friends,
A moth with a different appearance and charm for March wallpaper is - The ‘Rose Myrtle Lappet Moth’ - ‘Trabala vishnou’- named after deity Vishnu - is found in India, Sri Lanka, China, Bhutan, Bangladesh, Myanmar, Indonesia, & Japan and was recorded at Project Rahal.
It inhabits gardens, agro-forestry landscapes, and semi-natural woodland habitats.
The caterpillars are robust and densely setose (hairy), and may occur in different colour morphs. Their urticating hairs can cause mild skin irritation on contact. Larvae are polyphagous, feeding on a wide range of host plants including Poplar (Populus spp.), Castor (Ricinus communis), Jamun (Syzygium cumini), Pomegranate (Punica granatum), Rose (Rosa spp.) and Sandalwood (Santalum album) and few more.
Adults exhibit sexual dimorphism, with females generally larger than males. As with other members of Lasiocampidae, adults have stout bodies, well-developed scales, and bipectinate antennae i.e. comb-like antennae with fine side branches on both sides - especially prominent in males - helping them detect female scent (pheromones) from a distance. Its tent-like resting posture with half open wings is characteristic of lappet moths.
Ecologically, T. vishnou forms part of forest and agro-ecosystem food webs and is subject to natural biological control by parasitoid wasps such as Cotesia trabalae - whose larvae develop inside the host - a remarkable example of nature’s own biological control system.
A species both ornamental in appearance and ecologically significant, it illustrates the delicate balance between herbivory and regulation within tropical landscapes.
Regards,
Ketaki & Manasi
