  • The new species is highly adapted to hypogean life with very obvious troglobiomorphic features: unpigmented cuticle, an extraordinary lengthening of thorax and appendixes, multiplication of antennomeres and supernumerary placoid sensilla, not just in the apical antennomere but also in the preceding antennomeres.

  • Polar plots of long, smooth tapered and short steeply bent sensilla.

  • An insect helical, dielectric waveguide receiving antenna, called spine or sensilla responding to specific infrared wavelengths.

  • Dielectric waveguide modeling at 3.0 cm of the antenna sensilla of the lovebug, Plecia neartica Hardy.

  • DEET detection, the team attached recording electrodes to tiny taste hairs (sensilla) on the fly tongue and measured the taste-induced spikes of electrical activity resulting from nerve cells responding to DEET.


  • They then showed that when these receptors are expressed in the cells in the coeloconic sensilla, the cells respond to odors.


  • "It has been shown that cells in the coeloconic sensilla detect odors," Vosshall says.


  • Scientists have characterized the receptors that detect odors in two of these types but those receptors were mysteriously absent in the third, a swath of territory known as the coeloconic sensilla.


  • The team showed that these receptors, which the Vosshall lab named ionotropic receptors, do in fact explain how cells in coeloconic sensilla detect odors.


  • They found that the compound triggered a strong reaction in more than half of the insects '1300 sensilla, suggesting that the molecule drives the insect's behavior.

  • The beetles' infrared-detecting organs are mounted just behind the "hips" of their second pair of legs. Each one contains about 70 spherical sensors called sensillas. Inside the hard outer case of each sensilla is a chamber holding water. This expands when exposed to infrared radiation, exerting pressure on a nerve receptor at the base of the chamber.
