Miranha imbellis (Walker, 1858)

Miranha imbellis (Walker, 1858) can be found in Mexico and Central America.

Miranha imbellis is a member of the Zammarini tribe of cicadas, known for their Dracula/Vampire-style pronotal collars. One way to sort the M. imbellis from other members of this tribe is the infuscations (dark colorations) on its wings are relatively pale compared to Zammara cicadas, but not absent like the Odopoea azteca or Daza montezuma, and more obvious than Odopoea degiacomii. See this page to compare.

Scientific classification:
Family: Cicadidae
Subfamily: Cicadinae
Tribe: Zammarini
Genus: Miranha
Species: Miranha imbellis (Walker, 1858)

Miranha imbellis (Walker, 1858)

Miranha genus description by W. L. Distant:

Characters. — Head (including eves) a little narrower than base of mesonotum. the front moderately prominent, but only about half the length of vertex, lateral margins of vertex a little convex; pronotum about as long as mesonotum, its lateral margins ampliate and medially angulate ; abdomen about as long as space between apex of head and base of cruciform elevation, its lateral areas above moderately oblique, the tympanal orifices inwardly covered but outwardly exposed; abdomen beneath with the disk oblique on each side, but with the lateral margins broadly subreflected ; rostrum passing the posterior coxÅ“; opercula small, transverse; tarsi three-jointed ; tegmina and wings hyaline, the first with eight apical areas, and the basal cell considerably longer than broad.

Collared cicadas of Mexico, Central & South America

Most of the information on this website is focused on cicadas of the U.S.A. and Canada. There are plenty of cicadas south of the U.S., of course. Recently we started getting identification (ID) requests for cicadas of Mexico, and with the help of experts (Geert Goemans and Allen Sanborn) and a paper from the early 20th century, I was able to ID them all.

A large number of the IDs were for cicadas with pronounced pronotal collars. Many of these look like the same species, but they’re not. Many of these species are found from Mexico, throughout Central America down to South America.

On this page are six collared cicadas that exist in Mexico, Central America and South America. Illustrations come from Insecta. Rhynchota. Hemiptera-Homoptera. Vol. I by W. L. Distant and The Rev Canon W. W. Fowler, F.L.S. I updated the names to their current names (the source is about 100 years behind the times, expectedly so). Note that the illustrations from this document are of dead specimens, so the colors were faded at the time they were illustrated.

Daza montezuma (Walker, 1850)

Formerly Odopoea montezuma. This cicada is actually tourquois to pale blue when alive. Red eyes. No infuscation (coloration) in the wings. Link to original illustration..
