• [Apocynaceae:] Asclepias sp. (Seidenpflanze)
• [Apocynaceae:] Apocynum sp.

Hendrickson (2014: 57) fasst zu den USA zusammen: "The larvae are known to feed on milkweed (Asclepias species) (Covell 1984, Wagner 2005), but have been observed feeding on dogbane (Apocynum species) (Wagner 2005) and adults may be found on hostplants during the day (Covell 1984). The caterpillars typically prefer to feed on older shoots and so are rarely observed on the same shoots as monarch caterpillars (Danaus plexippus) which generally prefer younger shoots (Wagner 2005). These caterpillars are solitary in later instars, but are gregarious during instars 1–3 (Rea et al. 2003)."

3.1. Faunistik

E. egle ist natürlicherweise auf die USA und den Süden Kanadas beschränkt. Hendrickson (2014: 57) fasst zur Verbreitung der Art in den USA zusammen: "This species has the broadest range of the genus, spanning from Maine as far west as Minnesota, Iowa, and Missouri as well as a southern range spanning from North Carolina as far west as southeastern Arizona and as far south as the southernmost tip of the horn of Texas."

Die Autorin (S. 58) erwähnt aber auch eine Verschleppung nach Europa, speziel Ungarn: "There is one record of E. egle occurring in Szeged Hungary on 8 May 1983 and 28 May 1984, due to introduction (Kovács 1985). There have been no further records to suggest that establishment occurred." Die Primärquelle und die Details zu den beiden Funden in Szeged in Ungarn sind mir noch nicht bekannt. Sicher ist nur, dass es zu keiner Ansiedlung kam. Eine solche wäre in Europa allenfalls in Parks mit Asclepias-Pflanzungen ganz im Süden oder vor allem auf den Kanarischen Inseln möglich.
