We talk to Dr George McGavin about the insects and arthropods that are the topic of his new audiobook All Creatures Small and Great. How he decided what to write and talk about, his guests and who else he would have liked to have included and generally chat about the wonderful world of invertebrates. We discuss bed bugs, bitey ants, how locusts help us work out the causes of obesity and why you should never casually mention you may have found the worlds smallest insect to a journalist!
