I was surprised to learn that the Common house gecko, Hemidactylys frenatus, has expanded its native SE Asian range to include some Pacific Islands, Australia, South Africa, the southern USA and so on. It has even invaded Texas! I wonder how they move around?
I am a retired entomologist with a background in quarantine pests and invasive invertebrates. I studied zoology at Imperial College (University of London) and did a PhD on the population dynamics of a cereal aphid (Metopolophium dirhodum) in the UK. I spent 5 years with the British Antarctic Survey studing cold hardiness of Antarctic invertebates and 17 years with the Food and Environment Research Agency. My main interests now are natural history, photography, painting and bird watching.
