Entomology (Study of Bugs)/Sky-blue cockroach


Dear Ed,

I came across the image of a sky-blue cockroach on the internet: http://imgur.com/OAfal15.
However I am unable to find its official scientific name. Is this a real sort of cockroach? Or is it just another internet make-believe?

Thank you for answering this!!
Best Wishes,

Dear Johnnie - The cockroach appears to be real; the consensus among cockroach experts is that it either is an undescribed species in the genus Panchlora (see Cuban green cockroach) or in a very closely related genus (see http://tinyurl.com/jmuvav4). At any rate, at this time, it does not seem to have a generally accepted scientific name (Latin binomial).
Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
