So, you've been around a while, seen all sorts of things, and learned an awful lot about the world, solar system and Universe that we live in. But how well do you know it, really?

To scale and in order, these are the eight planets you know so well. There are the four rocky worlds of our inner solar system: Mercury, Venus, Earth, and Mars, and the four gas giants that dominate the outer solar system: Jupiter, Saturn, Uranus, and…

Eusattus dilatatus - dune darkling beetle (Tenebrionidae)
California, USA
Sand dunes are an unusual habitat, and the creatures found on them are equally odd. One of the more charismatic dune endemics is Eusattus dilatatus, a large darkling beetle found in southern California. This scavenging insect has long legs for digging and a waxy cuticle to prevent dessication.
Eusattus is not the easiest photographic subject. It seemed uncomfortable out in the open and would burrow as soon as I placed it on the sand. The series below spans 30 seconds.

In our front yard we've got a busy nest of Pogonomyrmex rugosus seed harvesting ants. Warming weather brought them out for the first time last week, and every now and again I go out to see what they're up to. Lots of digging, it seems.
Pogonomyrmex is greek for "Bearded Ant", named 150 years ago by Austrian myrmecologist Gustav Mayr for the thick brush of hairs on the underside of the head. Entomologists affectionately refer to these ubiquitous desert insects as "Pogos". What does the beard do?
It's a construction tool, and one that is especially helpful in dry, sandy climates. As anyone…

It seems therefore that a taste for collecting beetles is some indication of future success in life."
