<i><a href="https://en.wikipedia.org/wiki/Euchromia_polymena" class="extiw" title="w:Euchromia polymena">Euchromia polymena</a></i>, is a wasp moth (<a href="https://en.wikipedia.org/wiki/Euchromiini" class="extiw" title="w:Euchromiini">Euchromiini</a> tribe in <a href="https://en.wikipedia.org/wiki/Ctenuchinae" class="extiw" title="w:Ctenuchinae">Ctenuchinae</a> sub family) of the <a href="https://en.wikipedia.org/wiki/Arctiidae" class="extiw" title="w:Arctiidae">Arctiidae</a> family.  It is found in <a href="https://en.wikipedia.org/wiki/India" class="extiw" title="w:India">India</a> and South-eastern <a href="https://en.wikipedia.org/wiki/Asia" class="extiw" title="w:Asia">Asia</a>, as well as on <a href="https://en.wikipedia.org/wiki/Sumatra" class="extiw" title="w:Sumatra">Sumatra</a>, <a href="https://en.wikipedia.org/wiki/Java" class="extiw" title="w:Java">Java</a>, <a href="https://en.wikipedia.org/wiki/Sulawesi" class="extiw" title="w:Sulawesi">Sulawesi</a>, <a href="https://en.wikipedia.org/wiki/Peninsular_Malaysia" class="extiw" title="w:Peninsular Malaysia">Peninsular Malaysia</a>, <a href="https://en.wikipedia.org/wiki/Borneo" class="extiw" title="w:Borneo">Borneo</a> and the <a href="https://en.wikipedia.org/wiki/Philippines" class="extiw" title="w:Philippines">Philippines</a>. It is also present in the northern part of <a href="https://en.wikipedia.org/wiki/Western_Australia" class="extiw" title="w:Western Australia">Western Australia</a> and the <a href="https://en.wikipedia.org/wiki/Northern_Territory" class="extiw" title="w:Northern Territory">Northern Territory</a>.
<p>The adult moths have black wings with three large orange patches and two small blue marks on each forewing, a blue head, scarlet prothorax, and bands of blue and of scarlet on the abdomen. The abdomen is ringed basally with red, the next two segments are ringed blue, followed by two ringed red and then blue; in the otherwise very similar <i>E. elegantissima</i> there are three or four segments ringed red.
</p><p>Taxonomic notes: <sup id="cite_ref-1" class="reference"><a href="#cite_note-1">[1]</a></sup> It is at present unclear whether <i>elegantissima</i> and <i>polymena</i> are distinct or forms of the same species. No marked differences in the male genitalia have been noted. Seitz (1912-1913) placed <i>elegantissima</i> in synonymy with <i>polymena</i>, but the two taxa are separated in the current BMNH arrangement. The lack of distributional correlation might be understandable if the two taxa reflected climate, <i>polymena</i> occurring where there was a marked dry season.
