Taxonomy
Superfamily: Bombycoidea Family: SphingidaeSubfamily: SphinginaeTribe: SphinginiP3 Number: 890103 MONA Number: 7787.00
Comments: Six species of this genus occur in the US with a few more in the Neotropics. The genus appears to be an assemblage of several unrecognized genera and our three species eventually will probably all be placed in separate genera.
Species Status: Barcodes indicate that Ceratomia undulosa is a single, well-defined species in our area.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1948); Hodges (1971); Tuttle (2007)Technical Description, Immature Stages: Forbes (1948); Wagner (2005); Tuttle (2007)                                                                                 
Adult Markings: A large, grayish brown sphinx moth with double lines, several dark dashes, and a small white discal dot. This species is most likely to be confused with C. catalpae which is a smaller, duller brown species with a reduced reniform spot. It is also similar in at least size and shape to Manduca jasminearum, which is generally browner, has a prominent oblique dark dash, and lacks a discal dot. Sexes are similar.
Wingspan: 7.8 - 11 cm (Covell, 1984)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are green with seven pale oblique stripes on the sides of the abdomen, similar to those of Manduca and other sphinx moths; the head has a distinctive white band along its outer margin (Wagner, 2005). Pupation occurs underground.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Our most common Ceratomia (unless you live in a grove of Catalpa trees) and found everywhere in North Carolina.

Flight Comments: Apparently there are two broods but individuals flying in May and representing the first brood are uncommon. Later in the season this species together with Darapsa myron and Paonias excaecata make up the bulk of sphingid catches in light traps.
Habitats and Life History
Habitats: Our records come almost entirely from hardwood forests growing on rich soils, including brownwater river floodplains in the Coastal Plain, riparian and basic-mesic forests in the Piedmont and Mountains (including rich cove forests). Additionally, there are several records from the Great Dismal Swamp State Park, possibly associated with blackwater swamp species of Ash (i.e., Carolina or Pumpkin Ash).
Larval Host Plants: Larvae are stenophagous, feeding mainly on ash, but Wagner (2005) also lists Fringe Tree and lilac (also in the Oleaceae). In North Carolina, larvae have been found on White Ash and Green Ash. - View
Observation Methods: Originally recorded as feeding on flowers but the tongue is small and with no recent nectaring records, feeding is questionable. Adults come readily to lights but not to baits.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 S2S4
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This is another species that may be negatively impacted by the spread of the emerald ash borer. However, it is currently widespread and abundant and its potential use of host plants other than Ash may allow it to be spared. It's status should be monitored as the Emerald Ash Borer continues to spread in the state.
