Synanthedon arkansasensis
Duckworth & Eichlin, 1973
Arkansas Clearwing Moth
Synanthedon arkansasensis is a clearwing moth ( Sesiidae) described from Arkansas in 1973. Like other members of the , it exhibits -like mimicry with reduced wing scaling and a narrow, elongated body. The is part of a diverse group of borers whose larvae typically tunnel into woody plants. are and generally not attracted to light traps.

Identification
Clearwing moths in the Synanthedon are distinguished from other sesiids by a combination of morphological features including wing venation and genitalia structure. Specific identification of S. arkansasensis requires examination of diagnostic characters established in the original description; field identification to is unreliable without dissection or molecular analysis. The genus is characterized by narrow, mostly transparent wings with dark borders and a -mimicking body form.

Distribution
Known from the Nearctic region, with records from Arkansas and surrounding areas of the south-central United States. The precise range boundaries remain poorly documented due to limited survey effort and the general rarity of collection records for this .
Behavior
are and active during daylight hours. Like most clearwing moths, they are generally unresponsive to ultraviolet light traps used for Lepidoptera collection. lures have been used successfully to attract males of related Synanthedon .
Ecological Role
As a larval borer in woody plants, the likely functions as a primary consumer and contributes to nutrient cycling through wood decomposition. The -mimicking appearance of suggests aposematic or as a defense against .
Human Relevance

More Details
Taxonomic note
Described by Duckworth and Eichlin in 1973, this represents part of a taxonomically challenging group where species boundaries are often defined by subtle morphological differences in genitalia structure. The Synanthedon contains numerous species with limited biological data available.
Collection challenges
The exemplifies the general difficulty of surveying Sesiidae: are active during the day when collectors are less commonly deployed, they rarely come to standard light traps, and their -like appearance leads to frequent overlooking or misidentification in the field.
