Red, blue and black wasp Moth with white ‘boots’
July 12, 2010
This morning I was sitting on a bench in Sarchi, Costa Rica when a brightly coloured moth landed on my handed and proceeded to walk from hand to hand for roughly five minutes. After spending an hour doing some research I believe I’ve narrowed it down to the Cosmosoma genus and it most closely resembles the Scarlet Bodied Wasp Moth, but I’m interested to know the exact species.
Sarchi, Costa Rica
We agree that this is a Wasp Moth and it is most probably in the genus Cosmosoma. We are going to try to check with Julian Donahue, an expert in Arctiids and a traveler to Costa Rica, to see if he can provide information on the species.
Very much a distinct species, as I so very subtly pointed out to you last night.
The Natural History Museum’s Costa Rican specimens of this moth are identified as “Cosmosoma” sp. (?new), near regia.
Quotation marks because the moth is currently placed in Cosmosoma, but that may not be the correct genus.
Regia was described from Venezuela; a closely related species, bogotense, with reduced hyaline wing patches, was described from Colombia.
So it would be safe to say that this moth appears to be what is currently recognized as Cosmosoma regia (Schaus, 1894).

Hi Daniel and Edward:
Hopefully we can get a confirmation (or correction) from Julian Donahue, but I am going to suggest that it is Cosmosoma regia. I couldn’t find any online photos to compare to, but according to the identification keys and detailed descriptions provided by Hampson (1898) only C. regia and C. bogotense match most of the features visible in these excellent photos. Of the two, C. regia matches almost perfectly and is the only species with white tarsi, or ‘boots’. The localities given are Venezuela and Peru for C. regia and Colombia for C. bogotense, but I doubt that either of these represent an accurate range. Regards. Karl
