Below is a screen capture of a drosophila population being investigated: drosophila flies carry three sets of autosomes and two sex chromosomes their relatively fast life cycle and their ease of use made this common fruit fly an important historical model species, and they are still studied by geneticists today.

Drosophila melanogaster has been studied in genetic research laboratories for almost a century because the fruit fly has a short lifespan, a simple genome, and is easily made to reproduce in captivity it is a prime canidate for genetic research. The fruit fly drosophila melanogaster is a diurnal insect active during the day with consolidated sleep at night social interactions between pairs of flies have been shown to affect locomotor activity patterns, but effects on locomotion and sleep patterns have not been assessed for larger populations.
