Hedya separatana (Kearfott) (Tortricidae: Olethreutinae: Olethreutini)
Common name: pink-washed leafroller moth
FWL: 5.5-7.5 mm
Head black; thorax predominantly black with intermixed white and pink scales; thoracic tuft present, dark; forewing with basal two-thirds with ground color dark brown or black, fasciaefasciae:
plural of "fascia"
irregular, thin, white or whitish-pink, but heavily suffused with chalky blue gray scales; distaldistal:
farthest from body, distant from point of attachment
third of forewing white or whitish-pink with distinct black dot at distaldistal:
farthest from body, distant from point of attachment end of discal cell; male without forewing costal foldforewing costal fold:
a flap or fold at the base of the forewing that contains specialized sex scales
; hindwing dark gray.
Male genitalia are characterized by a well-developed, finger-like uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
; moderate sociisocii:
a pair of lightly sclerotized setose lobes
; valvaevalvae:
plural of "valva"
slender, curved, with robust rows of spine-like setae at base of dorsaldorsal:
upper, to the top, on the back 
edge of valvavalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation 
, distaldistal:
farthest from body, distant from point of attachment end of sacculussacculus:
the ventral margin of the male valva 
, and proximalproximal:
toward the base, nearest the body or point of attachment
edge of cuculluscucullus:
the distal portion of the male valva
. Female genitalia are characterized by a strongly raised groove-like medialmedial:
to the middle, center, toward center line 
portion of the lamella antevaginalis; and two scobinatescobinate:
rasplike
signa in the corpus bursaecorpus bursae:
a dilated membranous sac at the anterior end of the bursa copulatrix
.
No published descriptions exist for the larvae of Hedya separatana, but they likely are similar to other species of Hedya, such as H. chionosema and H. nubiferana.
Hedya separatana is very similar to H. ochroleucana and H. nubiferana, but can be differentiated from these two species by its smaller size and often (but not always) pink-washed distaldistal:
farthest from body, distant from point of attachment third of the forewing. Genitalia are distinct as well: males possess a tuft of long, spine-like setae at the base of the cuculluscucullus:
the distal portion of the male valva and females possess a pair of flat, scobinatescobinate:
rasplike signa in the corpus bursaecorpus bursae:
a dilated membranous sac at the anterior end of the bursa copulatrix.
Little is known of the biology of H. separatana beyond the host plants listed below. The record from larkspur (Delphinium sp.) is dubious. Larvae are leaf rollers; adults are most commonly collected between May and September, suggesting at least two generations per year. Adults can be found as early as April and as late as October in the southernmost portions of their range.
