Seeking Shelter ....

Now that the nights of growing colder a steady trickle of refugees are finding their way into the house from the garden. This female earwig is the latest arrival.

Earwigs very rarely unpack their elaborate fan-shaped wings and fly but when they do they are truly beautiful - take a look at this link!

Feeling the Pinch: Earwigs

I found this fine specimen of a male earwig Forficula auricularia under a rotten log today. You can tell it's a male by the curved pincers on the tail - the female's are much straighter. Earwigs can fly and have exquisite fan-shaped wings but they are tightly stowed away under those little wing cases and are very rarely unpacked. When this one suddenly found itself in the daylight its first instinct was to ....

... only those tail pincers protruded, capable of delivering a painful nip - although their other purpose is to clasp the female's pincers during tail-to-tail mating. Somewhere the female would have been hiding away guarding her eggs through the winter and when they hatch in spring she'll continue to guard the young during their early stages of growth - compared with most insects, earwigs are very attentive mothers.

Earwigs

If you grow dahlias or chrysanthemums for exhibiting in flower shows then this little insect, the earwig Forficula auricularia, is probably your mortal enemy. Earwigs like to rest with their flattened bodies concealed in crevices and the space between closely-packed flower petals is perfect. Unfortunately, while they’re there they tend to nibble the petals. But there is a more endearing side to earwig behaviour; unusually for insects, the females show strong maternal instincts towards their eggs and young. They lay their eggs in late summer and guard them through the winter, constantly licking them to keep them free from fungal infection, and then they feed the infant earwigs through those hazardous first days of life. The earwig in the picture is a male, identifiable by those large, curved tail forceps which are used for defence. When they’re threatened, as this one was, they raise their tails like scorpions, forceps at the ready. Females have straighter, more slender forceps and the other purpose of these organs is for gripping one another, during tail-to-tail mating manoeuvres. Earwigs can fly, but rarely do so. Behind the head there are two sets of wings. The front pair is short and rectangular and probably mainly functions to provide rigidity for the much larger, fan-shaped hind wings. Stowing away the large hind wings is a masterpiece of packaging that involves intricate folding, so maybe it’s not surprising that earwigs rarely take flight.
