Mosquito Habitat Photo Challenge

25 July to 25 August 2021

Short link to this page:


Scientists need your photos of mosquito larvae and land cover to help prevent mosquito-borne diseases.

The Global Learning and Observations to Benefit the Environment (GLOBE) Program invites citizen scientists from around the world to participate in the Mosquito Habitat Photo Challenge. This challenge combines Mosquito Habitat Mapper and Land Cover (two GLOBE Observer app tools) to document mosquito breeding habitats with photos.

GLOBE would like you to take photos of mosquito habitats, in either natural or artificial containers. If mosquito larvae are present, you are encouraged to photograph them with a magnifier (optional). Then, we’d like you to take photos of the land around the habitat location using the Land Cover tool.

Photos submitted during this challenge will be used to create automated classification programs that can identify mosquito larvae and the environments they prefer. Such computer programs can help prevent outbreaks of mosquito-borne disease.

How to participate:

  1. Download the GLOBE Observer app and register an account.
  2. Take photos of mosquito habitats and mosquito larvae using the Mosquito Habitat Mapper tool.
  3. Take photos of the same location using the Land Cover tool.

Even if you can't get outside to observe, you can still learn more about mosquitoes and land cover using the list of activities below. For partners leading formal or informal education programs surrounding the challenge, please contact us for templates to use for posters and presentations.


If you missed any of the  Mosquito Monday updates during the challenge, you can see them under GLOBE Observer News.

This handout describes the process of taking mosquito habitat and land cover observations during the Mosquito Habitat Photo Challenge, and gives tips about how to take high-quality mosquito larvae photos.

Mosquito Habitat Photo Challenge - Activities


Always follow guidelines from your local officials, and only participate in GLOBE activities or use the GLOBE Observer app if it is safe to do so.

As you complete activities or take observations, share your results with us through social media using #MosquitoChallenge new window or by tagging the GLOBE Program. 


  • Ask an expert about mosquitoes or land cover.
  • Teach a friend about mosquitoes or land cover (for example using the Mosquito Tellers activity new window.)
  • Share mosquito prevention tips.
