SIGNIFICANCE TO HUMANS
The household Lepidotrichidae was identified solely from Oligocene fossils till dwelling specimens have been found in northwestern California in 1959, and is represented as we speak solely by Tricholepidion gertschi. The household is thus of curiosity to scientists as a result of it’s thought of essentially the most primitive of the thysanurans and the hyperlink between primitive wingless and winged bugs.
