World of Insects Calendar

Every year, the ESA World of Insects Calendar showcases the stunning beauty of our arthropod peers 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.

Call for Photos: OPEN

Deadline for submissions: May 4, 2020

The photo submission period for the 2021 World of Insects Calendar is currently open. The Entomological Society of America seeks the finest examples of insect photography for inclusion in the next edition of the World of Insects Calendar. Submissions are now being accepted. Last year, more than 500 photos were submitted for consideration for the 2020 calendar.

Before submitting photos, please note the following guidelines:

  • Anyone with an interest in insects and photography may submit images for consideration for the calendar. There is no requirement for entrants to be ESA members or even entomologists.
  • Photos must be horizontal and rectangular, to fit the calendar dimensions. Vertical or square photos will not be accepted.
  • Photo files must be in JPG, JPEG, or PNG format (or these formats enclosed in a ZIP file).
  • Photos submitted for judging must be at least 2,000 pixels wide and may not exceed 10 MB in file size. However, to be eligible for inclusion in the World of Insects Calendar, winning entrants will be required to provide print-quality files of at least 11 inches wide at 300 dpi (dots per inch). Please do not submit photos for which you do not have print-quality versions.
  • Please include either an insect common name (e.g., honey bee) or species name (e.g., Apis mellifera) in each image filename. If you are unsure of the insect identification, please name the file with a general name (e.g., bee, ant).
  • Please remove all personally identifying information from both your images (e.g. watermarks or text overlays) and their filenames. Images will be matched to each entrant by ESA staff but provided to the judging committee anonymously.
  • Insects and related arthropods (arachnids, myriapods, entognathids) are welcome; however, please note that a maximum of one (1) non-insect image will be chosen for the calendar.
  • Photos must be of insects in natural settings. Photos of insects that are posed, mounted, fossilized, or imaged under a microscope will not be accepted.
  • A maximum of six (6) photos may be submitted by a single photographer. No more than two (2) images from any individual photographer will be published in the calendar.
  • Photos must be submitted via the World of Insects Calendar Photo Submission Form by 11:59 p.m. eastern time (U.S.) on May 4, 2020.

Also, winning photographers will be asked to:

  • Provide a print-quality version of the winning photo of at least 11 inches wide at 300 dpi (dots per inch).
  • Grant ESA permission to publish their photos in the calendar as well as on the ESA website and social media for the purposes of promoting the calendar. In all uses, photographers will be credited by name.
  • Optional: Write a concise paragraph to accompany the photograph in the calendar on the biology of the species or genus/family. (ESA staff and volunteers will write photo descriptions for photographers who do not feel adequately knowledgeable about the subject of their photos.)

Photos are evaluated by the ESA Committee on the World of Insects Calendar via a blind judging system so that no photographer names or other identifying information is known to the judges. Fourteen (14) images are selected (12 months plus inside front cover and back cover). Judging criteria include composition, color, and clarity, as well as entomological appeal. The intent of the judging process is to limit one (1) winning image per entrant to maximize photographer representation in the calendar. However, a maximum of two (2) images from a single entrant may be selected upon agreement of the judging committee to maintain quality standards or reasonable taxonomic diversity of images.

Entrants whose photos are selected for the calendar will be notified in July 2020.

For the 2020 calendar, more than 500 photo entries were submitted by nearly 130 insect photographers from around the globe. The 2020 cover photo captures a robber fly (Holcocephala fusca; Diptera: Asilidae) clinging to a leaf, taken by Jim Turner of Silver Spring, Maryland.

The 2020 calendar is available for purchase in the ESA bookstore. All proceeds from sales of the World of Insects Calendar directly benefit ESA's Chrysalis Fund, which fosters the future of entomology through grants for programs that teach kids about insect science.
