(Walker, 1856)
Florida Oakgall Moth, Florida Oakgall Borer Moth
Synanthedon sapygaeformis is a clearwing moth in the Sesiidae, commonly known as the Florida Oakgall or Florida Oakgall Borer Moth. A , S. sapygaeformis floridensis, has been documented in Florida with biological notes published in 1964. As with other sesiids, this exhibits mimicry through its transparent wings and hymenopteran-like appearance. The specific epithet 'sapygaeformis' references a resemblance to wasps in the Sapyga.

Identification
Distinguished from other clearwing moths by association with oak galls and geographic distribution centered in Florida. The S. sapygaeformis floridensis is recognized from Florida . Specific diagnostic features separating it from congeneric such as S. acerni and S. scitula require detailed examination and are not fully documented in available sources.
Images
Appearance
As a clearwing moth, possesses transparent areas on wings due to reduced scaling, with dark borders and . Body typically -like in form, with coloration suggesting hymenopteran mimicry. Specific color pattern details for this are not well documented in available sources.
