World of Insects Calendar

Every year, the ESA World of Insects Calendar showcases the stunning beauty of insects and related arthropods through striking, world-class photography.

Photographs are selected by the ESA Committee on the Insect Calendar and must be of the highest aesthetic and technical quality. A call for photos is announced early in the year for the following year's calendar, which is published each year in November.

New: In 2021, ESA launched a weekly "Arthropod Photo of the Week" feature on social media, for which submitted photos may also be considered. Follow along with "Arthropod Photo of the Week" via the #arthropodPOTW hashtag on TwitterFacebook, Instagram, and Mastodon.

Call for Photos: CLOSED

The photo submission period for the 2025 World of Insects Calendar closed May 12, 2024. 

The ESA Committee on the World of Insects Calendar will evaluate photos for their aesthetic and technical quality, and images for the 2025 calendar will be chosen in July 2024. All winning and non-winning entrants will be notified of the results in mid-July.

The 2025 World of Insects Calendar will be available for purchase in November 2024. Each attendee at 2024 Annual Meeting of the Entomological Society of America, November 10-13, in Phoenix, AZ will receive one free copy of the 2025 World of Insects Calendar. Additional copies may be purchased onsite or online.
