Isopod Field Trip
Many of us have childhood memories of touching a pillbug and watching it roll into a ball, thus earning the nicknames “pillbug” and “roly-poly”. Pillbugs and their cousin “sowbugs” are known collectively as terrestrial isopods. Fossil records indicate that terrestrial isopods shared the earth with dinosaurs during the Cretaceous period, 65-145 million years ago. Nowadays, 22 species of terrestrial isopods have been documented in Maryland throughout the year and from a wide variety of habitats. On this first-of-its-kind MBP field trip, we will focus on these fascinating crustaceans that play an important ecological role by eating decaying organic matter.
Join trip leader Dave Webb at Marshy Point Park in eastern Baltimore County for a short hike with several stops to search for terrestrial isopods (and other arthropods) that inhabit in and under decayed logs, leaf litter, and other hiding places. Along the way, Dave will discuss basic isopod anatomy, share tips on finding and identifying isopods, and point out features to photograph for documentation.
