A Survey of the Lepidoptera, Biogeograhy and Ecology of New Caledonia

I spent 4 months in New Caledonia in 1971 with the thing of constructing a quantitative survey of the night-flying macrolepidoptera with light-traps and an evaluation of the Rhopalocera and microlepidoptera.

In some parts of Brazil, up to 44 percent of the population test positive for antibodies to this virus. A bite from a midge can also deliver a parasitic nematode from the genus Mansonella; the tiny worms usually inhabit humans undetected, making diagnosis difficult but also making treatment less urgent. Scientists recently discovered that the nematodes require an abundant supply of bacteria in their own guts; after giving patients in one West African village a round of antibiotics, the bacteria inside the nematodes were killed off and the nematodes then died as well.

He stands on his head, drapes his abdomen across her mouth, and tries to quickly finish the business of copulation while she coats him in digestive juices and starts to nibble. If he’s not fast enough, he will, in fact, die for love. After a female black widow has mated once, she stores enough sperm to lay eggs for the rest of her life. She’ll create a series of egg cases over her one-­to-­two-­year lifespan, filling each one with hundreds of eggs, although only a few dozen may survive to adulthood.

Once it has a good grip, it begins rocking back and forth, working needlelike feeding organs called stylets into the skin. It bites gently, piercing the skin just enough to get the blood flowing. The stylets probe around under the skin in search of a good-­sized blood vessel to tap into. The bed bug’s saliva contains an anticoagulant to prevent clotting, so it can settle down and feed. If it is left alone to enjoy its meal, it will feed for about five minutes and then wander off. But if you were to swat at the bug in your sleep, it would probably move a short distance away and bite again, leading to a telltale series of three sequential puncture wounds.
