PHILADELPHIA – Ground wasps have been found in Wissahickon Valley Park recently, and the Friends of the Wissahickon group are warning park goers.

The group announced Aug. 4 that a ground wasp nest was found on the connector trail between Blue Bell and the Orange Trail.

Park goers are urged to avoid the area between Blue Bell Park and the Walnut Lane Bridge. Anyone who does chose to head through that part of the park should use caution.
