The Anaxyelidae are a wood wasp family within the Symphyta, containing only a single living species, Syntexis libocedrii, (also called the cedar wood wasp or incense-cedar wood wasp), though the family has an extensive Mesozoic fossil record; this species is thus a "living fossil".
 It has the remarkable behavior of ovipositing only in recently burnt incense-cedar ("Calocedrus"), red cedar ("Thuja") or juniper ("Juniperus"); the wood is often still smoldering when the wasp is laying its eggs, and the larvae develop in the wood.
 It occurs from the mountains of central California to southern British Columbia, but is very rarely seen, except by firefighters.

The Cedar River is a 338 mi river in Minnesota and Iowa.
 It is a tributary of the Iowa River, which flows to the Mississippi River.
 The Cedar River takes its name from the red cedar ("Juniperus virginiana") trees growing there, and was originally called the Red Cedar River by the Meskwaki.
 The first Mississippi steamboat reached Cedar Rapids, Iowa in 1844, and during the next decade, the Red Cedar (as it was still called) was an important commercial waterway.
