Swallowtail (Papilio machaon) Macaon

The swallowtail is a large and brightly coloured butterfly which is easily recognised. The main colour on upper and under wings is yellow with bands and veins of black. On closer inspection there are blue markings and a pair of red spots on the hindwing. The tail streamers are where it gained the common name, although occasionally one or both may have broken off.

The caterpillars of this species can be up to 5cm long. They have a glandular defense system against predation. On their necks is hidden a fork of brightly coloured retractable flesh, when raised this emits a foul smell to deter predators.

Summer insects in the Sierra de Grazalema

Summer time is when many insects reach the adult phase of their life. They may have spent months, even years as a larva, drab in colour and unable to move far, possibly living underwater or underground. Now, in this last stage of their lifecycle, they might be brightly coloured, able to fly or to emit sounds and so they become more obvious to us. Insects are a very important part of the food chain on which we depend.
