Re: [OM] IMG: From the Archives, an Adult Cicada

<<<I assume they see in monochrome through those RED eyes.

Most insects at least within their compound eyes have at least two 
photoreceptors types, often one in UV range.  So Cicada color vision may not be 
great but unlikely to be monochrome.
Monarchs are trichromatic like bees.  Bees do not see red though, IIRC but have 
a photoceptor in the UV range. One type of Swallowtail has 15 subtypes of 
photoreceptors.  Too bad I can't elicit help from them in optimizing color in 
photoshop.  Lab color would be a highly restricted color gamut for them.  As 
you can see there exists a wide range of color processing abilities in insects. 
  I don't know specifically about cicadas--perhaps Dean would know.

Nice image, BTW.
