Acute corrosion of the oral mucosa in a dog due to ingestion of Multicolored Asian Lady Beetles (Harmonia axyridis: Coccinellidae)

Toxicon. 2008 Aug 1;52(2):389-91. doi: 10.1016/j.toxicon.2008.05.010. Epub 2008 Jun 3.


A six-year old mixed-breed dog presented with severe trauma to the oral mucosa suggestive of chemical burn. Sixteen Harmonia axyridis (Coccinellidae) were removed from the oral cavity, which revealed trauma consistent with chemical burn. The beetles had become embedded in mucosa covering the hard palate and required manual removal. A diagnosis of beetle induced chemical burn was warranted and consistent with the nature of the chemical constituents of H. axyridis hemolymph.
