A tiger beetle larva, probably Cicindela hirticollis, sits at the mouth of its burrow awaiting a hapless arthropod passerby. Found along the shore of the Chesapeake Bay in Northampton County, Virginia.
This spring the day after final exams ended I was off to southern Utah to begin work on a summer research project on the Coral Pink Sand Dunes tiger beetle, Cicindela albissima. This was my third trip out to the dunes and as ever I was eager to see these small but spectacular insects. As I have mentioned before on the blog this species is only found within the Coral Pinks Sand Dunes state park, mainly withing a small conservation area (outlined below).
In the coming months I’ll write more on the research itself , but for now a few photos (and a video) of the beetles. Below is an image of an adult female – there are occasionally individuals which have an isolated dark stripe near the rear edge of the elytra.

My stay was originally was to be just under two weeks but as my departure date drew closer and there was no sign of rain (a key trigger for the emergence of 1st instar larvae) I chose to prolong my stay by another week. The day after my planned departure a front blew in and brought the first rain to the dunes in over a month. In the early hours of the next day I made the short trek out to the dunes and the 1st instar larvae were all over – just what I had hoped for.

for a blog named after tiger beetles it seems about time. This is Cicindela rufiventris, a common species found throughout the eastern US.

Not my best image, but one of, if not my first good shots of a tiger beetle. Getting this image was tough – I had to slowly crawl along the ground, trying to get close enough to get a good shot while hoping not to scare away the beetle.
