Xylophanes tersa, the tersa sphinx, is a moth of the family Sphingidae.The species was first described by Carl Linnaeus in 1771. It is found from the United States (Massachusetts south to southern Florida, west to Nebraska, New Mexico and southern Arizona), through Mexico, the West Indies and Central America and into parts of South America (including Bolivia, Paraguay, Argentina and Brazil).
In some sphingids, the pupa has a free proboscis, rather than being fused to the pupal case as is most common in the macrolepidoptera. [2] They have a cremaster at the tip of the abdomen. [5] Usually, they pupate off the host plant, in an underground chamber, among rocks, or in a loose cocoon. [5] In most species, the pupa is the overwintering ...

The caterpillar needs to be able to feed and to avoid being eaten and much of its morphology has evolved to facilitate these two functions. [59]: 108 After growth and ecdysis, the caterpillar enters into a sessile developmental stage called a pupa (or chrysalis) around which it may form a casing. The insect develops into the adult in the pupa ...
Only the discal spot, the basal section of the first postmedian line and the fourth postmedian line are standing out from the greyish-brown ground colour in most specimens. The pale yellow spots of the median band on the hindwing upperside are fewer and smaller than in Xylophanes tersa tersa and sometimes flushed with pink.
The length of the forewings is 36–41 mm. It is intermediate in appearance between Xylophanes aristor and Xylophanes tersa. There is a weakly developed golden medial line on the tegula. The upperside of the thorax has a grey medial band, bordered laterally and divided medially by brown lines.
Caterpillar hair has also been known to cause kerato-conjunctivitis. The sharp barbs on the end of caterpillar hairs can get lodged in soft tissues and mucous membranes such as the eyes. Once they enter such tissues, they can be difficult to extract, often exacerbating the problem as they migrate across the membrane. [34]
