South west summer brings dearth of wildlife
There are notable absences in nature. No butterflies, or almost none. My vigilant opposite in the Irish Times, Michael Viney, noted in his July 4 column that a group of 30 searchers walked 5km in a nature reserve in Donegal without seeing a single butterfly, but then came upon 10 species in a small area.
He commented: “Retreating to a hot spot, then spreading out when things get better; this is, apparently, how butterflies survive.” An interesting observation, and a relief to know. I’ve noticed, in some years, the near absence of certain species, and wondered how a new crop would be engendered to fly on the following year.
