Lioptilodes albistriolatus (Zeller, 1871)


Lioptilodes albistriolatus (Zeller, 1871) 

Fig. 2View Figures 2–9, 25a, bView Figures 25–28, 37View Figures 37–42.

Diagnosis. Adults are typically drab-gray with the forewing ground color composed of mixed drab-gray and white scales with fuscous spots. Abdomen with pale lateral stripes. The species is recognized by the small paired anterior and posterior fuscous dark spots at the base of the forewing cleft, and one at the middle of the discal cell, and a white costal dash along the costa at the base of the first lobe ( Fig. 2View Figures 2–9). The forewing discal cell is pleated from the middle of the discal cell to the cleft so that in live or unspread specimens, the paired fuscous dots and dark scales along the costa appear contiguous. Male genitalia with symmetrical simple valvae; phallus with aedeagus strongly curved, phallobase with short rounded coecum penis and well-developed ventral process ( Fig. 25a, bView Figures 25–28). Female genitalia ( Fig. 37View Figures 37–42) with posterior half of ductus bursae sclerotized, antrum not differentiated; paired signa thorn shaped.

Life history. Larvae feed in the flower heads of various composite genera including Baccharis  L., Conyza Less.  , Erigeron  L., Solidago  L., and Symphyotrichum Nees ( Matthews and Lott 2005)  , all of which occur in The Bahamas ( Correll and Correll 1982). In The Bahamas, adults were observed in association with flowers of Baccharis dioica Vahl.  Conyza canadensis  (L.) Cronq., an introduced weed, occurs throughout the islands and is also likely used in The Bahamas as it is in the USA.

Distribution. Widespread in the Neotropical and Nearctic Regions. Recorded in The Bahamas from Abaco, Andros, Cat, and Grand Bahama Islands. Previously reported from The Bahamas on North Andros Island ( Matthews et al. 2012).
