Ceratomia undulosa Sightings by Month

Conservation Status

• Global status: G5 (secure)

Reasons: “This seems to be by a substantial margin the most common of the North American ash-feeding Sphinginae, and it is among those that can persist on urban street trees. However, as with all of the ash-feeding Sphinginae this rank does not account for possible impacts of the emerald Ash Borer and reflects merely current status as of about 2011. Unless that pest is controlled this will be among the several Sphinginae that will be drastically reduced and may be at risk of extinction by the mid 2000s.”

• National status: N5 (secure)
• Indiana status: NR (not ranked)

Floral Associates

The Waved Sphinx caterpillars host on a small variety of trees, but specifically prefer members of Olive (Oleaceae) family which includes Ashes and Lilacs in Indiana. Adult moths mostly like do not feed.
