Phasmid
Definition:
(n.) Any orthopterous insect of the family Phasmidae, as a leaf insect or a stick insect.
Example Sentences:

(4) On their descent they found droppings that seemed too large to be from any other insect and decided to return at night when the phasmids were known to be active.
(5) The bat gene product can also antagonize the lambda cI repressor as shown by the observation that lambda pR phasmids are virulent on a homoimmune lysogen.
(6) The region available for recombination spans the homologous sequence shared by the plasmid and the phasmid.
