The adult Puritan tiger beetle is a fast runner and strong flier (9). Usually active during the day (3) (4), it actively pursues its invertebrate prey (5). Like other tiger beetles, it is a voracious hunter that is likely to be one of the dominant invertebrate predators in its habitat (2).
Although the colour and markings of the adult Puritan tiger beetle make it difficult to spot when not moving (5), it may be predated by dragonflies, robber flies (Asilidae species) and jumping spiders (Salticidae species) (2) (5).
The Puritan tiger beetle spends 23 months of its 2-year life cycle as a larva (5) (10). The larvae of this species create burrows where they lie in wait for passing invertebrate prey (4) (5) (10), firmly positioned at the mouth of the burrow by means of hooks on the abdomen (2) (4) (5). The burrows are closed for hibernation during the winter, as well as during the summer, probably to avoid parasitism by flies and wasps (5). In some locations, the burrows may be subject to flooding (2) (5).
The larvae of the Puritan tiger beetle pass through three developmental stages before pupation occurs around June of the second year (5), with the adults emerging several weeks later (3).
Mating in the adult Puritan tiger beetles begins in mid-July and continues until mid-August, when, their life cycles complete, the adults begin to die off. The female Puritan tiger beetle lays eggs individually just below the surface of the sand, and the eggs hatch after about a week, usually in late August or early September (3) (5) (10).
