Specimen #707

Aedeagus without lateral spines. Sacculus with basal cluster of about 9 pale spines. Valval neck has two opposite pads of dark spines. Hindwing base looks white but appears to be descaled there. Valvae would not stay spread for a photo.

Havelock, ON
Found in rock barrens on sandy soils.
Possibly a surprise prize from an otherwise lacklustre night. I had kind of dismissed this as O. merrickana at the time. The food plant is Bastard Toadflax - Comandra umbellata (which has been observed nearby).

Came to LepidLED.
Olethreutes fasciatana has a particular FW fringe pattern. The fringe at the apex is black, followed by 3 bands of white/black/white. The rest is usually dull brownish gray. The FW fringe in O. undulana is completely pale or suffuse gray. (https://bugguide.net/node/view/187772).

Endothenia montanana. Photographed near Consecon, Prince Edward county, Ontario on 14 June 2015. A unexpected lifer for me and rather a nice-looking Olethreutine I have to say. Like the charcoal and slaty tones of this one.

In jack pine (Pinus banksiana) area that burned last spring. A sand-encrusted silk-lined tube is attached to the stem of the sand cherry (Prunus pumila) plant on which the moth is perched. The tube-building habit for this species is described in this article: https://archive.org/details/entomologicalnew16acad/page/12/mode/1up?view=theater.
Same moth as https://www.inaturalist.org/observations/225336376.

This seems to be a perfect match to the species description by Brown & Jaeger (2014), with photos found at http://treatment.plazi.org/id/03C28783FFDC597FFF77F936764CFE4B

BOLD shows several records for Canada, though the species is not mentioned in Pohl's (2018) Checklist or in the recent Ontario Moth Checklist by Beadle and King.

According to the species description in Brown and Jaeger (2014), the Y-shaped silvery lines and orange scaling on the FW distinguish C. marita from all other previously described North American Cydia species.

ID features include:
-grayish basal 2/3 of wing, with suffused orange on outer 1/3
-Y-shaped silvery striata along costa
-two silvery transverse lines at midwing
-dark brown line along distal edge of wing margin, broken by white dash at M1
-gray marginal scales

Over 100 exuviae of Ophiogpmphus observed at foot of riffle; absent from shoreline of riffle itself. Five transitioning/emerging consisting of both sexes. Rusty snaketail here as well. No other exuviae found.
