On June 9, 2021, FODMer Ed Eder documented a new fly species, Strauzia longipennis, never before confirmed on a George Washington Memorial Parkway property.  Its common name is sunflower maggot fly because its primary host plant is the sunflower.  Adults typically emerge in June.

It was in the native plant area along Haul Road trail, the area where the Friends of Dyke Marsh planted over 4,000 native plants to support native insects, birds and other wildlife.

For the Parkway, it was fly species number 282 and a new family, Tephritidae, the peacock flies. Parkway officials added it to their database.

On June 21, 2021, Ed observed and photographed a Northern pearly-eye butterfly (Enodia anthedon) in Dyke Marsh. This is the first documentation of this butterfly species since the Friends of Dyke Marsh started the butterfly survey in 2016. This butterfly is typically found in damp deciduous woods, usually near streams or marshes, in mixed transition zone woodlands.
