In his description, Cholodkovsky says that it "differs from Chermes viridis in that its nymphs develop not on the needles but on the bark" of the larch^[5] and it "appears to belong to the exclusively parthenogenetic species and, what is particularly remarkable, lives exclusively on the larch".^[5]

It is found on the Korean Peninsula,^[1] and in Japan (listed as an injurious pest under the name Chermes laricicola).^[6]
