Juvenile Black Rat Snake

Edible, adj.: Good to eat, and wholesome to digest, as a worm to a toad, a toad to a snake, a snake to a pig, a pig to a man, and a man to a worm. ~Ambrose Bierce


Zebra Swallowtail ButterflyZebra Swallowtail Eurytides marcellus
Wingspan: 2 ½ - 4 inches

The Northern Virginia region's only "kite" swallowtail is the unmistakable Zebra Swallowtail.

No other butterfly has its triangle-shaped, zebra-striped wings, which taper to long, graceful tails.

Below, a brilliant red stripe slashes across the hindwing. The summer generation is larger and has proportionally wider stripes and longer tails than the spring generation.

Look for Zebras sailing along watercourses or nectaring nearby in marshes and fields.

Zebra caterpillars require pawpaw trees (Asimina triloba), a shrub or small tree that grows beneath taller trees in rich, damp woods.

Amazing Insect Tour

Zebra Conchylodes MothWhen: Saturday, June 16, from 1:00 to 3:00 pm

Where: Merrimac Farm Stone House Visitor Center, 15020 Deepwood Lane, directions

Stick insects, katydids, mantises, butterflies, moths and dragonflies are busy foraging and reproducing in fields and forests. They may be quiet, small and easy to pass by, but insects make the world go round. They pollinate plants, dispose of dead things and provide food for countless other animals.

Join walk leaders Judy Gallagher and Kim Hosen for a closer look at insects we discover in fields and forest edges at Merrimac Farm. For more information and to register (appreciated), email or call 703.499.4954.

Stream Restoration Talk

Swamp Milkweed1st Thursday Speaker Series

When: Thursday, July 5, 7:30–9:00 pm

Where: Bull Run Unitarian Church, 9350 Main Street, Manassas, directions

Speaker: Tom Dombrowski is an Environmental Engineer with Prince William County Department of Public Works Watershed Branch, specializing in wetlands, streams and environmental assessments.

Stable streams that meander through wooded areas in and near neighborhoods help create attractive communities, and provide important habitat to various flora and fauna. However, a stable stream is hard to find in developed areas and restoration/stabilization efforts can be complicated.

Stream restoration can be expensive and often may take years before the benefits are visible. PWC has completed several significant restorations and more are planned. How are streams selected for restoration? What are the goals? Participants will learn about the basic concepts and techniques of stream restoration projects, including criteria for selecting restoration sites and evaluating goal success.

This program is part of PWCA's Stream Stewards, more information is online HERE.
