Leaf mine - Stigmella myricafoliella

Leaf mine - Stigmella myricafoliella
Block Island, Washington County, Rhode Island, USA
August 25, 2015
On Myrica pensylvanica. Leaf mining Lepidoptera listed on HOSTS for M. pensylvanica are: Caloptilia flavella, Cameraria picturatella, and maybe Agonopterix walsinghamella, Psilocorsis cryptolechiella, and Dichomeris bipunctella (if they're miners.)

Moved from ID Request.

Of the five moths you listed, only the first two are leafminers--and there are at least five others on this host.

 
Wow
Exactly why I need help on these. I guess this should be a priority to raise next year, since MPG only has sightings from FL and GA and only one pinned image--no live ones. Plus, the only flight time data is March in FL, pretty useless for anywhere to the north. How would I rear one?

 
Rearing leafminers
The short answer is, put the leaf in a vial and wait. In the next couple of months I'm planning on putting a page on my website detailing my rearing techniques.

I've only found a single larva of this species; it was on Nantucket on August 4 (2012). I didn't manage to rear it, so I'm not sure when the adult would have emerged, but Erik van Nieukerken got a DNA barcode from the dead larva so I know that's what it was. Before that he was thinking this species might only occur in Florida, with Stigmella corylifoliella being responsible for similar mines to the north.

 
Thanks!
I'll be sure to look at the details in the spring! Hopefully I'll get one of these. I'd imagine there are quite a few, since bayberry is abundant here.
