Lone Star Tick (group)


Left to Right: unengorged female, 1/4 engorged, 1/2 engorged and fully engorged.  Notice how star continues relationship to mouthparts?  The star is part of the shield and remains consistent throughout the engorgement sequence.  Shields on all hard ticks are consistent in their relationship to the mouthparts.
