Size
Forewing length 4.5-5.1 mm (1).
Identification
See description and figures here.
Range
USA: from Maine, Illinois and northwest Arkansas south to central Florida and southern Louisiana (2)
Canada: Ontario (1)
Season
Adults fly in June and July in the North, early April to June farther South (2).
Food
Dichanthelium dichotomum (L.) Gould (Poaceae) (Braun, 1923, as Panicum dichotomum) (1)
Life Cycle
The larva mines a small basal leaf in the spring, eating out almost the entire substance of the leaf. Just before pupation, it enters one of the lower stem leaves, in which it makes a small inconspicuous mine, scarcely larger than the larva, but broadening at its anterior end towards the tip of the leaf, slightly inflated, and showing us a convexity on the upper surface of the leaf. Within this cavity, which is silk-lined, pupation takes place. Beyond the pupation chamber, the mines extends a short distance forwards, but is scarcely visible except at its end, where the epidermis is almost eaten through, permitting the emergence of the imago (Braun, 1923) (1).
Remarks
According to Frey & Boll (1876) the larvae mine on Zizania miliacea (Michx.) Doell & Aschers (Poaceae) in April and July. Further data of this host plant have not been found (1).
See Also
Externally similar to C. clandestinella, but differs by the presence of white median lines on the head and the thorax, by the golden brown ground color of the forewing and by the three silver streaks in the basal area which are positioned in an outwardly oblique row.
