#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.

iBehave Seminar Series talk by Prof. Dr. Eviatar Yemini – ibehave

The function and evolution of a genetic switch controlling sexually dimorphic eye differentiation in honeybees

Bee researchers at Heinrich Heine University Düsseldorf (HHU) headed by Professor Dr. Martin Beye have identified a new gene in honeybees, which is responsible for the dimorphic eye differentiation between males and females of the species. The researchers have now presented this gene and the evolutionary genetic conclusions they have drawn from it in the journal Nature Communications.
