Isidiella divitella
Isidiella divitella is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ).
Features
The moths reach a wingspan of 8.5 to 12.5 millimeters. The head shines white. The sensors shine brown and curled white hairs in the second half. The thorax shining white and gold on the sides. The tegulae shining golden and are lined with white back. The forewing shining golden and golden brown on the Costa loader. Between anal fold and wing inner edge there is an indistinct golden brown Basalstrich. The rest of the wing is largely drawing with Isidiella nickerlii identical, but the Costalstriche become more distinct and the raised, pale golden spots are smaller. The Apikalfleck is white.
The genital armature of the males is similar to that of Isidiella nickerli that Valven but are slimmer, the right Valvella is shorter and wider. The diameter of the ductus ejaculatoris at the confluence of the aedeagus is half as large as the largest diameter of the bulbous portion of the aedeagus.
The genital armature of females resembles that of Isidiella nickerli, but differs by only thin sclerotized posterior end of the ostium and the indistinct posterior sclerotization of sternite 7. The ductus bursae is shorter than the corpus bursae.
Similar Species
The two most significant differences of Isidiella divitella to Isidiella nickerlii are the white head and the broad white Dorsalstrich on the thorax.
Dissemination
Isidiella divitella is native to the western Mediterranean region ( southern France, Corsica, Sardinia, Spain, Portugal).
Biology
The caterpillars develop on Italian straw flower ( Helichrysum italicum ), Mediterranean Helichrysum ( Helichrysum stoechas ) and Holy herb ( Santolina ). On a stem they attach a spherical cocoon of a web of tubes extending to adjacent leaves where nate the caterpillars. The cocoon has the appearance of a plant gall, and is covered on the outside with vegetable hair. It is used during eating breaks as a hiding place and the adult caterpillars pupate therein. The moths fly from June to August.
