A highly magnified electron microscope image of an insect antenna – the common wasp (Vespula vulgaris). Insect antennae have individual sensilla – the long straw-like structures – which can detect small amounts of scent like sex pheromones.
The higher magnification in the inset shows another kind of pore-like cell (in the centre).
