I found this interesting looking structure attached to a tree trunk. Would you be able to identify it for me?
This is the ootheca or egg case of a Preying Mantis. We located similar looking images on Friends of Te Henui and on T.E.R:R.A.I.N where it the species is identified as Orthodera novaezealandiae and the following information is posted: “They lay eggs in foamy egg case called an ootheca. The ootheca has a woody appearance and has straight uniformed sides. They are usually attached to a leaf, stem, wall or fence. The young hatch out as small versions of the adult.”
