}} Amorpha is a monotypic moth genus in the family Sphingidae erected by Jacob Hübner in 1809. Its only species, Amorpha juglandis, the walnut sphinx, was first described by James Edward Smith in 1797. DistributionIt is native to North America, where it is distributed from the Atlantic Ocean to the Rocky Mountains in Canada and the United States. DescriptionThe wingspan is 45–75 mm. BiologyThe adult moth is nocturnal, active mainly during the early hours of the night. The caterpillar feeds on alder (Alnus), hickory (Carya), hazelnut (Corylus), beech (Fagus), walnut (Juglans), and hop-hornbeam (Ostrya) species. When attacked by a bird, the caterpillar produces a high-pitched whistle by expelling air from pair of spiracles in its abdomen. This antipredator adaptation may startle the bird, which may then reject the caterpillar.[2] References1. ^{{cite web|url=https://www.cate-sphingidae.org/taxonomy/Amorpha/juglandis.html |title=CATE Creating a Taxonomic eScience - Sphingidae |publisher=Cate-sphingidae.org |date= |accessdate=2011-11-01}}{{dead_link|date=September 2016|fix-attempted=yes}} {{Wikispecies|Amorpha}}2. ^{{cite journal |doi=10.1006/anbe.2001.1753 |title=Diel flight periodicity and the evolution of auditory defences in the Macrolepidoptera |year=2001 |last1=Fullard |first1=James H. |last2=Napoleone |first2=Nadia |journal=Animal Behaviour |volume=62 |issue=2 |pages=349}} Further reading
