Diagnosis. See comments under A. rhoifructella, regarding diagnosis based on external appearance of adults. Other diagnostic characters that differentiate the two species are presented in Table 1.
Adult (Fig. 2 A). External appearance as in A. rhoifructella, except for differences in forewing coloration as noted in diagnosis of that species. Male genitalia (Fig. 6). Valva a straight simple lobe, broadening rather abruptly near base, then nearly uniform in width to apex; vinculum symmetrical, anterior part forming a single slightly curved line in lateral aspect, symmetrically V-shaped, left and right margins each with narrow ventral keel in posterior half; juxta with rounded, symmetrical posterior margin; gnathos a transverse band with large, rounded medial lobe; phallus broad with truncate apex, straight in ventral view (Fig. 6 G). Female genitalia (Fig. 8). Papillae anales membranous, with setae of varying length; posterior apophysis slender, rodlike; anterior apophysis broadly triangular at base, narrowing to become rodlike; posterior margin of tergite 8 a narrow transverse band with large, rounded independent medial lobe; ostium bursae in transverse invagination, indistinct, with dense scales on either side; ductus bursae membranous, slender, bulbously enlarged at base; corpus bursae membranous, ovate, its surface foveolate, densely covered with short microtrichia except in area of signum; signum a transverse band with one large and two or more small thornlike projections on posterior margin; ductus seminalis originating near signum at anterior margin of unspined area of corpus; appendix bursae small, membranous.
Final-instar larva (Fig. 2 B). Length, 11 mm; color dull green; head orange brown; prothoracic shield blackish brown, sometimes with anterior margin yellowish brown; pinacula of most primary setae black, large and conspicuous. Chaetotaxy as in A. rhoifructella (Fig. 3).
Pupa. No consistent differences were found with that of A. rhoifructella (Fig. 4).
Larval damage (Fig. 2 C). As described for A. rhoifructella.
Phenology. Univoltine, overwintering as adult. Larvae have been collected in central Illinois from 13 May to 7 June, with adult emergence occurring from 30 May to 21 June.
Food plants. Apparently monophagous on Viburnum prunifolium in central Illinois. Also reared by Ilona Loser in Dane County, Wisconsin, from Viburnum nudum var. cassinoides (Linnaeus) Torrey & A. Gray. In Ontario, Canada, A consonella has been reared from Viburnum lentago Linnaeus (J.-F. Landry, in litt.).
Distribution. Type locality, Missouri; known to occur in Texas, Illinois and Wisconsin; also, descriptions by Kearfott (1904) and Wild (1942) of “ rhoifructella ” larvae collected on Viburnum in New Jersey and New York, respectively, diagnose A. consonella. In Canada, A. consonella has been confirmed from Ontario and Quebec (J.-F. Landry, in litt.).
