From: Reduced olfactory acuity in recently flightless insects suggests rapid regressive evolution
Odorant-evoked antennal responses are slower in wing-reduced than in full-winged stoneflies. A Antennal response onset time (time to 10% of signal maximum after valve opening, includes the time odorant need to reach the antenna), and B response offset time (time to 10% of signal maximum after the maximum). Grey: full-winged; green: wing-reduced. Circles show individual antennae. Horizontal black lines show means and vertical black lines show 95% credible intervals. * or ** greater than 95% or 99% certainty for differences between antennae of full-winged and wing-reduced stoneflies
