Delaware State Macroinvertebrate

Stonefly

(Order Plecoptera)

Adopted on May 4, 2005.

On May 4, 2005, the Stonefly (Order Plecoptera) was designated as Delaware's State macroinvertebrate, because it is an indicator of the excellent water quality in the State. The designation of the stonefly was a means whereby Delaware State government could recognize the importance of excellent water quality and the vital role played by healthy aquatic ecosystems in Delaware.

Designating a State macroinvertebrate is a highly appropriate means to raise public awareness of water quality issues, and complement citizen action programs like Delaware Stream Watch. Through their participation in the Delaware Stream Watch Program, the designation of the stonefly as the official State macroinvertebrate was supported by the following schools:

Gunning-Bedford Middle School, Salesianum High School, Delcastle Technical High School, Dickinson High School Environmental Club, The Independence School, Springer Middle School, St. Andrews School, and The Charter School of Wilmington.

By designating the stonefly as its State macroinvertebrate, Delaware once again demonstrated its leadership as the First State, because currently, no other state in the United States has designated an official State macroinvertebrate to accompany their State symbols, such as their State flag, State flower, State bird, State bug, State butterfly and State marine animal.
