(238ANlar) Anurophorus laricis (Nicolet, 1842)

  *corticinus (Bourlet, 1842)

Anurophorus laricis is a widespread and common species often found under bark.  It is one of the climbing Collembola, often found in collections of canopy insects, and does not seem to be fussy about the species it climbs; alien conifers have been found to support substantial numbers of these, along with Entomobrya, Orchesella, Vertagopus and Lepidocyrtus species.  It is dark blue with 8+8 ocelli but these are difficult to see among the dense pigment on the head. Specimens need to be heavily cleared to see the eyes. However Anurophorus laricis does not possess a furca and there is no empodial appendage on the foot. The largest specimen in the NHM (1.8 mm) was collected by Peter Lawrence from a site near to Inchiquin Lough, Eire in July 1960. The tibiotarsi each possess several clavate tenant setae (Fig. 2). There are a few literature records of Anurophorus laricis from wet Sphagnum bogs, but these probably represent other Anurophorus (eg A. unguiculus), and should be checked for an empodium
