Sharp spines, strange sex

I know many arachnophobes; in fact I live with one. But being afraid of spiders of the genus Micrathena is about as rational as being afraid of a diamond brooch. These animals are jewelry come alive, harmless, and each more ornate and vividly colored than the other. There are about 100 known species of Micrathena (Araneidae),…

How to swim on dry land

Namibia is one of the driest places on the planet. It is home to the Namib Desert, the oldest perpetually dry place on Earth, which has endured arid conditions for at least the last 55 million years. Most places in the Namib receive less than 10 mm of rain per year, some even less, and…

Each developing wasp larva consumes a single egg in the ootheca (which can contain several hundred eggs), but in some areas the number of these insects can be so high that it is a miracle that any mantids…
