   <\/strong>  Jeremy Tatum writes:  My recent plea for a photograph of a genuine Silverfish <\/strong>Lepisma saccharinum<\/em><\/strong> <\/strong>brought an interesting response from Libby Avis in Port Alberni.  <\/p>\n

 <\/p>\n

     First, two photographs of a Silverfish <\/strong>Lepisma saccharinum <\/em><\/strong>from 2020 August 26.   Note that the Silverfish has much shorter cerci and epiproct (the things at the tail-end!) than other lepismatids.<\/p>\n

 <\/p>\n

   Next – Ctenolepisma<\/em><\/strong>, from 2012.  The genus Ctenolepisma <\/em>was formerly regarded as feminine, but it has now been declared to be neuter.  Therefore, writes Jeremy Tatum,what I have been calling C. longicaudata<\/em> on this site is now to be called C. longicaudatum.<\/em>  <\/em>However, this photograph below may be a different species, namely   C. lineatum<\/em><\/strong>.<\/strong>   <\/strong>Notice the four rows of pale dots.   I think (not sure) that longicaudatum<\/em> may have a longer abdomen) than lineatum<\/em>, and possibly longer legs, too.<\/p>\n

 <\/p>\n

 <\/strong>I should probably sometime  (if I can find the time) go through earlier photographs of Ctenolepisma<\/em> on this site, and see if we can determine which of the two species they are.<\/p>\n

 <\/p>\n

   As for English names,  originally “The” Silverfish  was Lepisma saccharina <\/em>(now saccharinum<\/em>), and “The” Firebrat was Thermobia domestica<\/em>.  Other species in the family are called variously by different authors  either adjective silverfish or adjective firebrat.<\/p>\n

 <\/p>\n

   But we haven’t finished yet.  On 2020 October 29, Rick Avis found the interesting creature below in the Avis’s yard.   A blind and colourless three-pronged bristletail in a related Family,  Nicoletiidae:<\/p>\n

   The photograph below shows the three caudal (tail) appendages.  The middle one is called the epiproct<\/em>.  The outer two are cerci<\/em>.  <\/p>\n

 <\/p>\n

 <\/p>\n

Classification:<\/strong>  <\/strong>None of the creatures shown or mentioned in this posting are classed today as insects.  They are not in the Class Insecta:<\/p>\n

 <\/p>\n

I believe it goes something like this <\/p>\n

 <\/p>\n

Phylum:     Arthropoda<\/p>\n

  Subphylum:    Hexapoda<\/p>\n

      Class:                  Entognatha<\/p>\n

            Subclass:          Zygentoma<\/p>\n

                    Order:            Thysanura<\/p>\n

                         Families:       Lepismatidae,  Nicoletiidae<\/p>\n

 <\/p>\n

The Order Zygentoma are “Three-pronged Bristletails”.     “Jumping Bristletails” (Microcoryphia), and “Two-pronged Bristletails” (Diplura) are different Orders.<\/p>\n

 <\/p>\n

  Variations on this are to be found in the literature.  For example, some authors treat Zygentoma as an Order, and do not use the word Thysanura. <\/p>\n
