Letter 1 – Orange Spotted Tiger Moth from Australia, but what species?????
while it’s bogong season here in Sydney, Australia, the attached is something I grew up always calling a “tiger moth”. I don’t know much else about it, but they come out in summer. I seem to recall there being plagues of them in the 1980s, but these days you’re lucky if you see a handful each year. They’re about an inch long. Cheers,
We quickly located your Tiger Moth, more specifically, Orange Spotted Tiger Moth, Ceryx guttulosa, on the wonderful GeoCities website. This species, like many other Tiger Moths, is a wasp mimic. Just as we thought we had this one solved, we noticed a second page on the GeoCities site called Orange Spotted Tiger Moth 2. This second species, Amata annulata, looks remarkably like the first. Now we are not certain which is correct, but thankfully, both have the same common name.
Letter 2 – Agreeable Tiger Moth
Subject: spotted moth in garden Location: Baltimore, MD March 13, 2014 1:13 pm after planting a garden in Baltimore Maryland (downtown!) We started getting a bunch of strange bugs – is this just a standard moth, or something special? Late summer months. Thanks! Signature: Jet Setter Hi Jet Setter, This Tiger Moth is in the genus Spilosoma, and based on the number of black spots and the location of the sighting, we believe the best match is the Agreeable Tiger Moth, Spilosoma congrua, that we found pictured on BugGuide. Picturing the abdomen would be helpful in the identification, because BugGuide notes: “Adult: S. virginica has yellow markings on the abdomen, while S. congrua‘s abdomen is pure white.”
Letter 3 – Male Tiger Moth from Indonesia displays Coremata
Subject: Large Horned Moth Geographic location of the bug: Indonesia (?) Date: 10/20/2017 Time: 06:06 AM EDT Stumbled on this on facebook, wondering what this moth is. How you want your letter signed: Thomas Dear Thomas, Early this year we received an image of a similar looking Tiger Moth, also from Indonesia, and Arctiid expert Julian Donahue informed us: “the widespread Asian Creatonotos transiens displaying his coremata (androconia are specialized scent scales usually confined to the wings). You can see images here: https://hiveminer.com/Tags/creatonotostransiens/Recent and also if you Google the congeneric Creatonotos gangis you will see images of similar coremata.” Based on this Real Monstrosities image, we believe your species is the latter one. That site states: “Creatonotos is a genus containing about 10 species of moth found in parts of Africa, southeast Asia and Australia. Two species are particularly widespread and well known: C. transiens with their pale, orange abdomen and wings entirely white save for a few carefully-placed, black dots, and the more dramatic C. gangis. Their abdomens are red and they have lovely black stripes on their wings, as if someone was testing a brush before practising some Chinese calligraphy.”
Letter 4 – Male Tiger Moth from Malaysia revealing his coremata
Subject: Moth??? Geographic location of the bug: Maylasia Indochina Date: 07/05/2019 Time: 08:49 PM EDT Your letter to the bugman: Video on FB by a friend…. How you want your letter signed: YFS Dear YFS, This is a male Tiger Moth, Creatonotos transiens, revealing his coremata, a specialized scent organ. Seems this image is getting some internet buzz.
