  abstract = {{U}nderstanding the relative contributions of the shape of a sensory organ and the arrangement of receptors to the overall performance of the organ has long been a challenge for sensory biologists. {W}e tackled this issue using the wind-sensing system of crickets, the cerci, two conical abdominal appendages covered with arrays of filiform hairs. {S}canning electron microscopy coupled with 3{D} reconstruction methods were used for mapping of all cercal filiform hairs. {T}he hairs are arranged according to their diameter in a way that avoids collisions with neighbours during hair deflection: long hairs are regularly spaced, whereas short hairs are both randomly and densely distributed. {P}article image velocimetry showed that the variation in diameter of the cercus along its length modifies the pattern of fluid velocities. {H}airs are subject to higher air flow amplitudes at the base than at the apex of the cercus. {T}he relative importance of interactions between receptors and the air flow around the organ may explain the performance of the cricket's cercal system: it is characterised by a high density of statistically non-interacting short hairs located at the base of the cercus where sensitivity to air currents is the highest.},
