Dix WMA- Sleepy Orange Colony
Cumberland County, NJ

Lead a tour of the Dix WMA Sleepy Orange colony today and welcomed participants from our South Jersey Butterfly Blog and from Citizens United to Protect The Maurice River organization.

An amazing day was enjoyed by everyone.

This colony began with the discovery of three individuals in 2016 (one male and two females) and a thought that maybe….This thought was supported with the discovery of host plant growing in the preserve.

In 2017 overwintering individuals were found in June and soon caterpillars. 2017 saw 33 individuals flying in the growing and safeguarded senna patch. Then in 2018 the count rose to 89 individuals. Today, with the 2019 survey, we found 152 individuals! In addition to this amazing colony of Sleepy Oranges, an even greater sized colony of Cloudless Sulphurs exists in this same area. Today, we count 298 Cloudless Sulphurs.

Both species have historically been scarce, late season vagrants and never found in large numbers. History is being re-written with this special area.
