Faking it as a survival strategy

Cheats and Deceits: How animals and plants exploit and mislead. By Martin Stevens. Published by Oxford University Press (2016). Last year, on a trip to Devon, I saw my first ever oil beetle (Meloe proscarabaeus). She was beautiful. Her black carapace glistened violet and blue in the sunlight. She was gravid and crawling along the footpath in search of a place to… Read More Faking it as a survival strategy

The Little Bombardier

Best stay out of the way. There are more than 500 species of Bombardier beetle (a form of ground beetle – Carbidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini all displaying the highly effective defence mechanism of releasing a superheated pulsing jet of noxious chemicals sprayed directly at would-be predators.  I have always been fascinated by the ammunition of… Read More The Little Bombardier

What’s (not just) brown and sticky? Adaptive radiation in Stick and Leaf Insects in the order Phasmatodea.

The order Phasmatodea contains more than 3,000 extant species of insect found throughout the world, especially the warmer zones. These herbivorous (mostly arboreal) insects are most well-known for their crypsis, or camouflage, where their colour, shape and behaviour enable them to masquerade as twigs or leaves (hence their common names of stick and leaf insects).… Read More What’s (not just) brown and sticky? Adaptive radiation in Stick and Leaf Insects in the order Phasmatodea.

Hawk moths and evolutionary predictions

Commonly known as Hawk Moths, Sphinx Moths and Hornworms, these moths are important pollinators of orchids and other flowers. Nectar tubes and hawk moth tongue lengths are often associated; Xanthopan morganii praedicta (centre) was famously predicted to exist by Charles Darwin and Alfred Russel Wallace based on the length of the nectar spur of the Madagascan Christmas star orchid… Read More Hawk moths and evolutionary predictions
