We get a number of enquiries each year from the general public asking us to identify various insects that they have found in their homes or gardens. The majority of these enquiries are of British insects (as you might expect) but we also get a handful of more exotic and exciting insects that people have seen whilst on their travels in other countries.
The photograph above was sent to us by Mr M. Steadman and was taken whilst on holiday in Turkey.

The large and very impressive insect pictured is Saga pedo- a species of cricket belonging to the family Tettigonidae. It is an unusual species for a number of reasons but in particular because it is predatory. Nearly all crickets are herbivores, feeding on a wide variety of plant species. Saga pedo feeds primarily on insects and has been known to cannabilise members of its own species. There are even a number of reports of this species hunting small reptiles and young birds.

This species is also unusual because it appears to reproduce asexually by parthenogenesis. Specimens are therefore female and can be identified by the long spear shaped ovipositor at the rear of their body (as seen in the photograph above). There has yet to be a reliable sighting of a male specimen of Saga pedo.
