Diagnosis. Small ochreous­brown to dark brown species with indistinct wing markings, often with a slightly darkened subapical area.
Description. Adult (figs. 11–14). Wingspan 10–12 mm. Labial palpus creamy ochreous to ochreous suffused brown on the outer side, segment 3 usually lighter than segment 2. Antenna fuscous ringed with ochre. Head with frons ochreous; vertex, thorax and tegula as forewing. Forewing ochreous brown; costa with a blackish spot near the base, otherwise not markedly darkened; plical and discal stigmata rather indistinct, first discal beyond second plical; costal and tornal patches ochreous and indistinct, fused to form an outwardly angulated fascia; subapical area heavily suffused with blackish scales; termen with an indistinct lining of blackish scales; cilia dark ochreous gray with indistinct ciliary lines and yellowish tips. Hindwing pale brownish, darker towards apex, cilia concolorous.
Variation. Specimens vary from dark ochreous brown with fairly distinct stigmata and a darkened subapical area, to uniformly dark brown without clear wing markings. Very occasionally the stigmata are followed by indistinct streaks of pale scales.
Similar species. Very dark forms resemble B. similis. In well­preserved material it will always be possible to distinguish the brownish ground color with ochreous markings of B. hodgesi from the blackish ground color with whitish markings that characterize B. similis.
Due to their variation, there are no absolute rules for distinguishing B. hodgesi from B. branella or B. altitudophila. On average B. hodgesi is slightly smaller and less vividly marked. In B. branella and B. altitudophila the costal edge of the forewing is often distinctly darkened, a rare feature in B. hodgesi. Specimens having the subapical area distinctly darkened are usually B. hodgesi. In a geographically restricted area it will be possible to distinguish B. branella from B. hodgesi without examination of the genitalia. In case of B. hodgesi and B. altitudophila the labels show that they never occur on the same location, suggesting different habitats.
Male genitalia (figs. 28–31, 41, 61–66). Uncus subrectangular, rather small. Socius with 3–4 setae. Gnathos slender and long with a 120 degree bend in the first third. Thornshield triangular with 50–80, usually small, spikes. Margin of vinculum bent at or before 1/3 (fig. 41).
The male genitalia show considerable variation. The gnathos can vary from very slen­ der (fig. 63) to clearly thickened halfway (fig. 66), thus resembling B. similis (q.v.), while the bend may be more gradual and continue until half­way. In a lateral view the gnathos of B. hodgesi does not exceed 250 µm in height whereas the gnathos of B. branella and B. altitudophila measures 300–350 µm in height (figs. 66–69, 70–73). In northeastern USA and southeastern Canada, the aedeagus often displays a characteristic sharp bend underneath the apex, which is also remarkably broad (arrowhead in fig. 29). In other areas the aedeagus resembles that of B. branella and B. altitudophila.
Female genitalia (fig. 48). Segment VIII ventrally with crescent­shaped lamella postvaginalis, microtrichia and a shallow median invagination. Distal end of the ventral groove marked by a small sclerotized extension. Dorsal side of segment VIII without a median tongue. Signum large, about twice as long as wide, strongly tapering toward the distal end, with stout spikes on the corners and a clear pointed extension distal to the last spikes. Easily recognized by the shape of the signum in combination with the distal end of the ventral groove.
Biology. Early stages unknown. In the USA adults were found from mid­March to early October in California, whereas in Canada moths were collected from late June to mid­September. This indicates that in the southern part of its range there may be two generations, whereas in the northern part there probably is just one generation.
Distribution (fig. 78). B. hodgesi is common along the west coast of the USA. Elsewhere it is far more local, though when present it is often common. In Canada only recorded from the extreme south.
Etymology. A noun in genitive case. The species is dedicated to R.W. Hodges in honor of his many contributions to our knowledge of the Nearctic Lepidoptera fauna and his kind support of our work.
