To calculate the duty factor, a threshold velocity (5% to 10% of the peak velocity) was set above which the proleg velocity increased monotonically for at least 300 ms at the start of the swing; the duration above this threshold was defined as swing phase and that below it the stance.
Each step in the proleg-bearing segments was composed of a stance phase, during which the prolegs were attached to the substrate by the cuticular hooks (crochets); and a swing phase, during which the crochets were unhooked from the substrate, raised, and moved forward along with the segment as part of a crawl.
For many scholars, the proof of Grotius' modernity is his conviction that there would be a law of nature by which to govern human affairs "even if we should concede that which cannot be conceded without the utmost wickedness, that there is no God" (JBP, proleg.

Head-to-head Asynarchus encounters with Limnephilus and conspecifics often involved proleg wrestling and biting, and occasionally escalated into intraguild predation or cannibalism.
He did diagnose species using the anal proleg chaetotaxy, but as pointed out by Stehr (1987), this segment has the most confusing homology of any part of the caterpillar body.
Intraspecific variation is common and the number of sensilla often increases progressively from the proleg to the metaleg on mature larvae of various dytiscid taxa [11, 16-20].
All trochanters had anteroventral series of natotory sensilla although this series was less developed on the proleg.
