Researchers Raise Maggots on Chicken Blood to Save Darwin’s Finches

Backyard Chickens Harbor Greater Diversity of Ticks, Mites, and Lice than Farm-raised Chickens

And though they may indulge in […]

Forensic Entomologists Mite Start Looking at Acarids for Clues


By Meredith Swett Walker In 1879, long before TV shows like CSI and Bones created a generation of armchair forensic entomologists, Jean Pierre Mégnin, one of the first scientists to use insect evidence to aid death investigations, examined the desiccated body of a female infant found in a vacant lot in Paris. “The mummy of […]
