Zenodoxus mexicanus
Beutenmüller, 1897
Zenodoxus mexicanus is a clearwing moth ( Sesiidae) described by Beutenmüller in 1897. The Zenodoxus belongs to the Tinthiinae, a group of sesiid characterized by their -mimicking appearance and activity patterns. This occurs in the Nearctic and Neotropical regions, with the specific epithet suggesting a Mexican distribution. Clearwing moths in this family are typically associated with woody plants, with larvae often boring into stems or roots.

Identification
Identification to requires examination of genitalia and wing venation patterns. Zenodoxus can be distinguished from related in Tinthiini by combinations of wing pattern elements, body proportions, and male genital structure. The species Z. mexicanus would be separated from by specific pattern elements on the wings and body, though published diagnostic features are not readily accessible. Specimens in collections should be compared with type material.

Appearance
As a member of Sesiidae, this exhibits the 's characteristic clearwing : wings with reduced scaling that creates transparent areas, a -like body form with narrow waist, and often banded coloration mimicking Hymenoptera. The specific appearance of Z. mexicanus has not been described in detail in available sources. of Tinthiinae typically have relatively broad clear areas on the wings compared to other sesiid .
Distribution
Recorded from Nearctic and Neotropical regions. The specific epithet and patterns suggest primary occurrence in Mexico and potentially adjacent areas of the southwestern United States. Six observation records exist in iNaturalist, though precise localities are not specified in available data.
Behavior
are and exhibit -mimicry typical of Sesiidae, including rapid, erratic patterns that resemble those of stinging Hymenoptera. This mimicry provides protection from vertebrate .
Ecological Role
Larvae function as stem and root borers in woody plants, contributing to nutrient cycling and creating for other organisms in dead and dying plant material. serve as of flowers visited during nectar feeding.

Taxonomic note
The Zenodoxus is classified in the tribe Tinthiini within Tinthiinae. This tribe contains genera primarily distributed in the Old World and New World tropics and subtropics. The 's classification within Cossoidea reflects its relationship to carpenter moths and relatives.
