( bioluminescence) / the light takes a few minutes to switch on or off .
The beetles rarely feed / the female can glow for a few weeks until she mates / dying soon
after laying her eggs which hatch in 30-45days / the Larvae live for 2 years ,
feeding on snails , then pupating into the adult beetle .
