Wax-tail hopper

One day last year, when I was in Costa Rica’s Barbilla National Park, the manager of the park came to me and said that he had just found the strangest “mariposa nocturna.” What he showed me sitting on one of the beams of the station’s building was indeed strange, but it wasn’t a moth –…

The eventual usefulness of stuff

I admit it, I am a pack rat. Or at least it may appear so to the untrained eye. I hate throwing things away, but empty orange juice bottles can be used to make great flash diffusers; one of the dozens of loose, mismatched screws will eventually prove itself priceless by fixing my tripod head;…

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…

Rats in New Zealand, earthworms in New England, wild boars on New Britain, Wasmannia ants on New Caledonia (can you see a pattern?), they all have been introduced by people to new places, sometimes accidentally,…
