Calycomyza verbenae (Hering)

( Fig. 119 )

Material examined. IOWA: Allamakee Co., Red Oak Prairie (43°14'13.43"N, 91° 7'8.58"W), 16.vii.2015, em . 1.viii.2015, C.S. Eiseman, ex Verbena urticifolia , #CSE1920, CNC564727–564729 (1♂ 2♀); NORTH CAROLINA: Durham Co., Durham, Sandy Creek Park , 12.viii.2016, em . 1.ix.2016, T.S. Feldman, ex Verbena brasiliensis , #CSE2957, CNC638905 (1♂).

Hosts. Verbenaceae : Glandularia bipinnatifida (Nutt.) Nutt. var. ciliata (Benth.) B.L. Turner, G. × hybrida (Groenl. & Rümpler) G.L. Nesom & Pruski , Verbena * brasiliensis Vell. , V. neomexicana (A. Gray) Small, V. * urticifolia L., “ Verbena ” cultivated varieties ( Frick 1956). We have found probable mines of Calycomyza verbenae on V. stricta Vent.

Leaf mine. ( Fig. 119 ) Whitish, quickly turning brown; initially narrow and following the leaf margin, expanding to a blotch; frass either in scattered black grains or dark and liquidy, spread throughout.

Puparium. Brown; formed outside the mine.

Distribution. USA: AZ ( Frick 1956), DC ( Frick 1956), IL ( Frick 1956), IN ( Frick 1956), *IA, FL ( Spencer 1990), NJ ( Frick 1956), NM, *NC, OH ( Frick 1956). Frick’s (1956) records of GA, MD, MS, NY, and PA require confirmation; those of MO and TX, and some from NM represent misidentifications (see comments under Calycomyza avira ). We have seen probable mines of C. verbenae in KS, MA, and MD.
