#Springtail #Orchesella #cincta is up to 4 mm long, native to #Europe/Canada and is #herbivorous/ fungi-bacteriovorous, #living e.g.in dead plant tissue. Specimen below: on #deadwood with island-like #fungalgrowth, mites, e.g. #Linopodes, and i.a. #isopods.
G. Ernsting & J. A. Isaaks (2002) found the #dimorphic #gendersize with smaller males being due to growth inhibition by #spermatophore development.
