Harris's pine hawk moth

 young larva is remarkable because of its large, high head terminating in a 

 conspicuous cone. Just before the last molt the heail is triangular, conical,

 line becoming yellow anteriorly, below the spiracles. This larva inay be 

 easily recognized by its conspicuous striping.
