Identification and Appearance

Contributed by Zhao J

As with most Calcaritermes species, workers, presoldiers and some nymphs and soldiers can be differentiated from a small rasp near the end of the pronotum. Soldiers may be differentiated from sympatric Cryptotermes species due to the smooth texture of the head and the possession of U shaped depression on the dorsal-anterior portion of the head. In Cryptotermes , the front of the head is concave, with many wrinkles and lacks the defined U-shaped depression. Alates can be differentiated from the median vein on the forewing; it is scletorized and lacks cross veins connecting it to the costal veins, additionally the membrane is covered in small bumps. If wings are not available, C. nearcticus tends to be much darker in colouration (black/dark-brown v. brown to light brown) All Calcaritermes (with the exception of C. temnocephalus ) possess a raised patch of scales (metanotal rasp) on the pseudergate, soldier and nymph castes. It is speculated that this may be used to hold microbes to aid in the breakdown of the wood they infest similar to bark beetles and their relationship with fungi. It has also been noted that these Calcaritermes use their frass to line gallery walls.

About Cockroaches and Termites: the wider group

Order-level background for Blattodea, the group containing Calcaritermes nearcticus. Species-specific details appear above.

Group overview

Blattodea includes ~4,600 cockroach species and ~3,000 termite species. Only about 30 cockroach species are associated with human habitats - less than 1% of all species.

Ecological role of the group

Termites contribute ~40% of soil arthropod biomass globally, far exceeding ants at ~10%. Cockroaches are ancient insects dating back 320 million years and are critical decomposers in tropical forest ecosystems, recycling leaf litter and dead wood.

Economic and practical significance of the group

Termites cause $5-30 billion in damage to structures in the U.S. annually. They damage approximately 600,000 American homes each year, with average repair costs of $3,000-$17,000. A subterranean termite colony can consume one pound of wood per day.

Recorded sources for this group: USDA, Orkin, Today's Homeowner, PNAS soil biomass study. Imported estimates may describe particular regions or reporting periods.
