Ecdytolopha Zeller (Tortricidae: Olethreutinae: Grapholitini)
The genus Ecdytolopha consists of 15 described species and ranges from Peru, north through Central America, the Caribbean, the U.S. to southern Canada.
Forewings are dark brown basally and light gray or white apically with a dark spot near the tornustornus:
the junction of the termen and dorsum of the wing 
in many species. Male genitalia are distinguished by the following characters: tegumentegumen:
dorsal section of the transverse ring in male genitalia; often heavily sclerotized 
rounded; uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
and sociisocii:
a pair of lightly sclerotized setose lobes
absent; valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
elongate, cuculluscucullus:
the distal portion of the male valva
densely setosesetose:
covered with setae
; and vesica with numerous deciduous cornuticornutus:
spines used to anchor the male vesica in the female bursa during copulation
. Female genitalia are distinguished by two signasignum:
a sclerotized projection or patch on the interior of the corpus bursae
in the corpus bursaecorpus bursae:
a dilated membranous sac at the anterior end of the bursa copulatrix
, and the location of the ostiumostium:
see ostium bursae 
, which is usually located in a deep invagination of sternum VII. Adamski and Brown (2001) provide keys to males and females.
Larvae are similar to other species in the Cryptophlebia-Ecdytolopha group, with an enlarged L-pinaculum on the prothoraxprothorax:
the most anterior thoracic segment
that extends beneath (and usually beyond) the spiracle. Larvae of Gymnandrosoma can be separated from those of Ecdytolopha by the distance between the V setae on A9: approximately the same as the distance between Vs on A8 in Ecdytolopha and 1.2-2.0 times the distance between Vs on A8 in Gymnandrosoma.
Two species of Ecdytolopha are treated on this site. Ecdytolopha fabivora (Meyrick) (formerly placed in Cydia) is a significant pest of beans (lima beans, string beans, soybeans) in Central and South America. The native species, E. insiticiana Zeller, is known as the locust twig borer in economic literature. Larvae feed within new growth on locust and can cause tree disfigurement.
There are many records of Ecdytolopha larval interceptions at U.S. ports of entry; however, most of these probably refer to Gymnandrosoma, as species such as G. aurantianum were placed in Ecdytolopha prior to 2001.
