Create habitat to help us reintroduce an extinct butterfly!

29 June 2019

Time: 10 am - 2 pm 

Help Friends of Onkaparinga Park Inc. plant special seedlings in the recreation park to provide habitat for the Yellowish Sedge-skipper. This native butterfly is regionally extinct in metropolitan Adelaide due to the absence of large stands of native Thatching Grass (Gahnia filum), which is listed as Vulnerable. 

This planting is part of a large-scale Gahnia revegetation project in and adjacent to the park this winter, after which we plan to reintroduce this butterfly once the sedges are mature. This is your chance to help with this special project.

The Yellowish Sedge-skipper uses the thatching grass to lodge its eggs; larvae once hatched then use the sedge for food and shelter until the butterfly emerges. The mature butterflies forage on nectar producing plants like Swamp Paperbark, gum trees and Common Boobialla. 

This is a family friendly and FREE event:

  • Morning tea, snacks and lunch provided.
  • All tools and safety equipment supplied.
  • Please wear closed shoes (gumboots if wet), long-sleeve shirt and a hat.
  • Water is available to fill up your bottles.
  • BYO chair please.

This project is an Adelaide and Mount Lofty Ranges NRM Board levy funded project.
