The Giraffe Weevil (Trachelophorus giraffa) of Madagascar is only one inch long but it has a very long neck which it uses to build nests. The neck looks like a red and black mechanical digger than a sensible product of evolution. This baked bean-sized beetle with a tiny head and furry antennae is like nothing else on Earth.
The male uses its extended neck to fight with other males, at which point they look like two construction vehicles at war.
The female's neck is almost three times shorter than male's. She uses her neck and powerful legs to roll a leaf into a tight cigar shape. Among
other things, she creates a kind of velcro strip which holds the nest together. This helps protect the egg while it incubates. One pinhead-sized, lemon-colored egg is laid inside the tube. Then she puts the lead nest in a safe spot in a tree or on a forest floor.
Amazingly, this insect has counterparts in New Zealand known as giraffe weevils.
The conservation status of the giraffe weevil is currently undetermined.
