Autumn: The season of pretty moths!
I love autumnal moths! as the leaves on the trees change from green to yellow and gold, the moths that fly at that time of year are often that colour too, mimicking the changes so as to stay camouflaged and safe.
This beauty is the Centre-barred sallow Atethmia centrago, a species which is moderately common in the south, but more local in the north. It is on the wing in August and September, and the larval food plant is Ash. I have not caught one in my garden for 3 years, so I was really pleased to get this one last night.
Autumn is also the season of Oak leaf galls, and here the leaf is covered in Spangle galls.
The cynipid wasp Neuroterus quercusbaccarum has both agamic and bisexual generations, which cause 2 different galls on Oak. The males and females emerge in June from current galls, which look like currants, and can be on both the leaves and catkins of oak trees. After mating the eggs are laid in the lower epidermis of oak leaves, these develop into spangle galls over winter, and the insects emerge in April and lay their eggs in either the catkins or lower epidermis of the leaves which develop into currant galls..and so it goes on..fascinating isn't it?
