Vertagopus cinereus is a widespread and common greyish-brown species that reaches a length of 1.5 mm. Almost all the records are from the trunks of trees, under dead bark and lichens, and in bird nests. Vertagopus spp. are typical members of canopy Collembola communities, along with Entomobrya, Lepidocyrtus, Orchesella and Pogonognathellus.
Tibiotarsi 1, 2 and 3 possess 2:3:3 clavate tenant setae respectively and the mucro has four teeth. The furca of Vertagopus cinereus is relatively shorter than that of the bluish-violet Vertagopus arboreus. In addition, on the ventral side of the thorax, Vertagopus cinereus has 3-10 + 3-10 setae on each of th2 and th3, and a group of 5-12 ventral setae on the second abdominal segment (abd2). Vertagopus arboreus does NOT possess ventral setae on th2, th3 or abd2.
