Curious about the bugs around us? Plan on participating in the "Summer of Bugs" at Valley Forge National Historical Park, where an inventory of the park's bugs will be assembled this summer

The park staff is partnering with researchers from the Academy of Natural Sciences of Drexel University to inventory the park's terrestrial invertebrates, better known as "land bugs." Together, the park and the academy invite those interested in learning about and contributing to the research to act as "citizen scientists" by observing and participating in two 24-hour BioBlitz events and a summer-long invertebrate "photoblitz." Activities are available for "scientists" of all ages and experience levels.

The park will kick off the Summer of Bugs on May 30 with a 24-hour BioBlitz based in the park's Education Center. Base camp will be open to the public from 2 p.m. '“ 5:30 p.m. on Friday, May 30, and from 8 a.m. '“ 12 p.m. on Saturday, May 31 with a special photography workshop from 8 a.m. '“ 10 a.m. You can follow the project this summer and share your discoveries on Twitter by using the hashtag, #summerofbugs.

"The BioBlitzs will help the park collect data on a group of animals for which the park has very little information," said Amy Ruhe, the park's biologist. "Terrestrial invertebrates represent our last major data gap. Conducting blitzs during two different seasons will provide the greatest opportunity to catalogue the variety of species in the park and enable more volunteers to participate in the activities."

All events are free and open to the public. Select events during the August BioBlitz require advanced registration and have recommended age and skill levels. For more information on the August BioBlitz and how to sign up to be a citizen scientist, visit the park's website.

Spring BioBlitz, May 30-31

Academy experts and amateur entomologists will begin their 24-hour field search for terrestrial invertebrates at noon on May 30. Researchers back at base camp, the park's Education Center, will catalogue specimens and keep an ongoing count of species reported. Base camp will be open to the public for observation and conversations with the researchers from 2 p.m. '“ 5:30 p.m. on Friday, May 30, and from 8 a.m. '“ 12 p.m. on Saturday, May 31. At 8  a.m. Saturday the park will host a photography workshop featuring macro-photography and include an introduction to

In addition to the BioBlitzs, park visitors can become citizen scientists by documenting their invertebrate observations throughout the summer at, an online species database for naturalists of all skill levels to share their observations. The entomologists at the Academy of Natural Sciences of Drexel University will help identify citizen observations and add the records to the Summer of Bugs inventory. Find the Summer of Bugs project online or download the iNaturalist app for quick uploads in the field.

The Academy of Natural Sciences of Drexel University is a world-class natural history museum dedicated to advancing research, education, and public engagement in biodiversity and environmental science. Learn more about the Academy at its website.
