Jeremy Tatum sends a photograph of a creature found in his bathroom this morning. It belongs to the Order Thysanura (Zygentoma of some authors), Three-pronged Bristletails. Taxonomists don’t seem to have settled whether or not they belong in the Class Insecta. The three species most commonly encountered indoors are the Firebrat Thermobia domestica, the Silverfish Lepisma saccharina and the one below, Ctenolepisma longicaudata, whose English name varies from author to author. Some authors spell the specific names of some or all of them –um rather than –a. I find that the Firebrat is by far the commonest, followed by C. longicaudata. I have yet to see Lepisma saccharina in Victoria. T.domestica and C. longicaudata like warm places; L. saccharina prefers cool places. I keep my apartment fairly warm, which may be why I have yet to see L. saccharina.
