I made a specimen of this individual and flipped it over to get a view of the mouthparts, which project outward after death--in life they were kept in line with, and below, the antennae. Shows the following characteristic(s) of the family Phryganeidae (1):

• maxillary palpi with 4 segments in male, 5 in female

This one has five segments, I believe, and that makes it a female--there is a very short fifth segment there at the base. See guide page for details. Corrections welcome--I have no experience with caddisflies!
