October is a very strange time of year – September seems like an extension of summer, but colder, and then very suddenly October arrives and the flowers of summer begin to die off, the leaves yellow, or redden, or both, and fall off deciduous trees as the nights grow longer than the days. Everywhere gets gradually more muddy as leaves, flowers and berries decay on the ground. But there is still a lot to see amid all the nostalgia of another year growing to an end.
At this time of year our swallows, the Barn Swallow (Hirundo rustica), tend to perch for long periods to rest their weary muscles before making their autumn migrations. There were definitely fewer of them around Wicklow this summer, which is slightly worrying as something must be preventing them arriving safely in Wicklow.
Ironically our autumn was better than our summer this year, although not quite as warm, although certainly more stable. Eventually the annual arrival of big dragonflies occurred, the Migrant or Autumn Hawkers (Aesna mixta) and there are still a few around, although very difficult to photograph or video as they fly. I usually watch one land and slowly approach to get a good photo. If you move slow they will remain still. But there are some other very interesting insects around, and some are both interesting and slightly creepy, such as this one:
Burying Beetles are quite closely related to chafer beetles (like the Cockchafer) and dung beetles, like the Common Dor Beetle. However, unlike these beetles, Burying Beetles lay their eggs in corpses which they find in the countryside, and they actually bury the animals they find underground. They are very intelligent creatures and very recently it was discovered (with the aid of special cameras) that they keep their larvae in nests and will feed them mouth-to-mouth, as birds do. Even more remarkable, the young ‘tweet’ when they’re hungry. This extremely handsome species is Necrophorus investigator (but there are many very similar ones and some even quite different. Watch out for them this autumn as they fly across the deep night skies.
