Adoxophyes furcatana (Walker) (Tortricidae: Tortricinae: Archipini)
FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe
: 7.5-10.5 mm
Adults are pale yellow with light brown fasciaefascia:
a dark transverse band on the forewing
and a network of light brown streaks along and between veins. Hindwings are white. Males have a forewing costal foldforewing costal fold:
a flap or fold at the base of the forewing that contains specialized sex scales
.
Male genitalia are characterized by a spatulatespatulate:
spoonlike, narrow basally and enlarged and rounded apically
uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
; an incomplete, finely spined transtilla; and large, rounded membranous valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
. Female genitalia are characterized by a long, broad, straight ductus bursaeductus bursae:
a membranous tube connecting the ostium bursae to the corpus bursae
; and a short, daggar-like signumsignum:
a sclerotized projection or patch on the interior of the corpus bursae
near the base of the corpus bursaecorpus bursae:
a dilated membranous sac at the anterior end of the bursa copulatrix
.
Larval morphology is undocumented for this species.
Adoxophyes negundana and A. furcatana are the only two representatives of the genus Adoxophyes in North America. These two species are difficult to separate using forewing pattern. In general, the median fasciafascia:
a dark transverse band on the forewing is narrower in A. furcatana, although this character does not appear to be consistent across all individuals. Freeman (1958)Freeman (1958):
Freeman, T. N. 1958. The Archipinae of North America (Lepidoptera: Tortricidae). Canadian Entomologist, Supplement 7 (Vol. 90): 1-89. states that male genitalia of A. furcatana have more cornuticornutus:
spines used to anchor the male vesica in the female bursa during copulation
(greater than four) and less sharply elbowed gnathosgnathos:
a narrow bandlike structure that joins the posterolateral edges of the tegumen and supports the anal tube
arms than those of A. negundana. Both species of Nearctic Adoxophyes are similar to Adoxophyes orana and might be confused with this Palearctic species if it were discovered in North America. It is not known if Nearctic Adoxophyes are attracted to A. orana pheromone.
Adults are present June to August. Larvae feed in rolled sycamore (Platanus) leaves.
