Ixodes holocyclus tick engorgement stages

Comparison of the stages of engorgement of the Ixodes holocyclus tick (Australian paralysis tick). Although these pictures are not to the same scale, the scutum can be used to compare the relative sizes because the size of the “shield” (scutum) does not change as the female tick engorges.
