Life Cycle

Complete Metamorphosis
The female will hunt for a tarantula spider to serve as food for the larva.  She will sting the spider causing its permanent paralysis.  The spider (if not already inside of its burrow) will be dragged into the hole.  She will lay an egg on the spider and seal the burrow.  The larva will hatch attaching to the spider and sucks out the internal fluid over a period of several months.
