National Moth Week offers backyard activities for safe science

The ninth annual National Moth Week, which this week will be July 18-26, invites novice and experienced “moth-ers,” alike, to observe moths in their own backyards and contribute to scientific knowledge as part of one of the world’s largest citizen science projects.

National Moth Week (NMW) offers the opportunity to learn about nighttime nature from the safety of backyards and gardens; porches, decks and balconies – anywhere a light can be turned on.


Free registration of private and public moth-watching events is encouraged on the NMW website in order to show where moths are being observed around the world. Private street addresses are never displayed. All participants will receive a certificate of participation designed by Ecuadorean artist Belen Mena of the NMW team.


“This year’s National Moth Week may not feature as many traditional public moth nights as in the past, but it’s still possible to observe and learn about moths while social distancing,” said Liti Haramaty, co-founder of National Moth Week, in a prepared statement. “All you need is an outdoor light source shining on a wall, door or white sheet. And don’t forget your camera.”


In addition to using lights, moth-ers also can attract moths by coating tree trunks with a sticky, sweet mixture of fruit and stale beer. Searching for caterpillars and day-flying moths is a good activity for daytime. The NMW website offers tips on attracting moths.


Participants are invited to contribute photos and data to NMW partner websites, as well as the NMW Flickr group, which now has over 100,000 moth photos from around the world. Moth observations submitted to, a site for sharing observations in the natural world, will be added to the NMW project on that site. Last year, over 27,000 moth observations were posted on iNaturalist.


Since it was established in 2012, NMW has inspired thousands of public and private moth-watching and educational events around the world in over 80 countries and all 50 U.S. states, according to the statement. Sites have included national parks and monuments, museums and local recreation areas, private backyards and front porches – wherever there’s a light and a place for them to land.


Last year, hundreds of National Moth Week events were registered around the world, including all 50 states and 47 countries.


“Moth diversity is astonishing and with a little effort it’s amazing what can be found in a backyard or local park,” NMW co-founder David Moskowitz said in the statement. “Some of my most exciting moth adventures have been in my own small backyard. Exploring yours is sure to yield moth treasures that are just waiting to be found.”


National Moth Week was founded by the Friends of the East Brunswick Environmental Commission, a nonprofit organization dedicated to environmental education and conservation. It is now one of the most widespread citizen science projects in the world. It is coordinated by volunteers in New Jersey, New York, Tennessee, Washington State, Ecuador, India and Hong Kong.
