pectinicornis = 'comb-horned'
common name reflects seasonal occurrence, in contrast with the Spring Fishfly, C. rastricornis
Antennae pectinate in both sexes (compared to C. rastricornis where female antennae are serrate); head and pronotum with pale markings on dark background; flight period later in the season than in C. rastricornis (1)

See Also
Head and pronotum have yellowish markings on dark brown background, as opposed to dark markings on light brown background found on C. rastricornis. Antennae of both sexes in this species are always pectinate, compared to C. rastricornis where females have serrate antennae and males have pectinate antennae. Also, note later flight (summer) of C. pectinicornis in most of the east. C. rastricornis typically flies in spring.
