Cricket Crawl 2013 - Evening Sound Census of Singing Insects - Overlea

  • Aug 23, 2013 · 8:00 PM
  • Maryland Naturalist Center












 Join ecologist Charlie Davis for an evening walk through the Overlea neighborhood to listen for the songs of insects.  We may catch a glimpse the singers—crickets and katydids—as we stop to make minute-long observations of eight target species. 

 Our group will send in observations, and they’ll be mapped online in real-time, along with those of other observers around the Baltimore/DC region.   Cricket Crawl is an evening sound census of the late summer crickets and katydids, which will help scientists to document the distribution of these often overlooked insects.

You can preview the songs of the eight target species at:

RAINDATE: August 24 - Check the website if it's rainy.

 If you want to participate in your own backyard, neighborhood, or park, instead, just follow the steps below:


 1.      Go outside: Walk outside—in the city, your backyard, or at a local park—between 8:15 pm and midnight on August 23rd.  Bring along your family, friends and neighbors—the more the merrier!  Make note of your general location (street address, intersection, latitude/longitude).   

2.      Listen:  Once you’ve picked a location, listen for one minute.

3.      Identify: Did you hear one of our 8 target species? Each one has a unique call.  You can learn the calls by going to our website ( or attending a “Songs of Insects” walk ( prior to the event. You only need to write down which species you heard; you don’t need to count how many you think are out there.


4.     Contact us:  Send in your results immediately by calling:[masked] and leaving a voice message. You can text your observations:[masked]-7732. You can email your results, photos, sound files, etc.: [masked].  Or send us a tweet: Twitter @speciesobs

5.      Include this information:  Your name; the location of your count (be specific: address or nearest intersection); list of species you detected; start time of the Count; a story or observation that you think people might like to know about.

6.      Visit our website to see the data as it’s mapped in real time as you do your count.  We hope to have the results go live during the night: 

Enjoy the sounds of summer and make a difference!
