There are only a handful of cockroach species that are adapted to live indoors with us. This one will only live indoors if the indoors in question contains warm humid air and moist soil with plants in it. Perhaps that explains the common name "greenhouse cockroach" Pycnoscelus surinamensis*. This species also goes by the name "Surinam cockroach," maintaining the long held tradition of naming pest roaches after places that are NOT where they came from.

Surinam roaches surely occur in Suriname (a former Dutch colony on the northeast coast of South America you goon), as they occur everywhere on earth with the conditions described above. They are thought to be native to Asia, down around Malaysia somewhere, and spread around the world with tropical plants. These roaches are burrowers, so it would be very easy for one or more to hide in the rootball of a Ficus or Lychee. And one is all that is needed to establish a colony, because these insects practice parthenogenesis--giving birth without sex. In fact, in North America, no one has yet found a male Surinam roach. A few have been found in Australia, but all female colonies appear to be the norm. The one pictured here is a wingless subadult; adult females grow tan wings over their dark brown abdomen.
