A possible new species for the Maritime Ecozone:
GRACILLARIIDAE Gracillariinae: Micrurapteryx salicifoliella - 0647 Willow Leafblotch Miner
UNB Woodlot, Fredericton, 14 October 2015.
I had no idea what this flat silken structure on a willow leaf was, so I sent it in to Charley E at BugGuide. The answer came back today: It "appears to be" a cocoon of Micrurapteryx salicifoliella. I removed the contents of the cocoon at home and photographed the remains, which appears to be a dead larva. The small structure associated with the larva is the cocoon of a parasitoid wasp, according to Charley.
Not mentioned in the MEZ document, no images for BugGuide and MPG for our area.
Image #3 shows the underside of the larva.
Nice images and information Chris!!
Fantastic find Chris!! Getting close up and personal in the image too! Congrats on a new Species for the maritimes :)
It's still a tentative id based on an image. Tony may or may not accept it.
