A hot day and at this time of year one when you need to take care in the full sun. I was in the office for much of the morning, which was at least cooler. At lunchtime I went outside, hoping to see some hoverflies and soldierflies on the hemlock water-dropwort, but all I saw was bees. I think it was too hot for many insects, on these kind of days they often sit out the hottest part of the day in the shade and can be found clinging to the underside of leaves.
A number of people have commented on the lack of butterflies in recent days, it is true there are not a lot, but this is not that unusual at this time of year. The spring species have mostly finished and the high summer species are just starting, the “gap” is often bridged by lots of white butterflies, but this year they have been quiet scarce. At Blashford the mid-summer butterflies are the browns and the meadow brown are just starting to appear in numbers now. They do not bask with wings open very much once the day has warmed, up so it was no surprise that they were all sitting with wings closed today.
Meadow brown has just one generation a year and they will fly from now until early September. Some species, like small tortoiseshell and comma have two generations, with the second over-wintering as an adult hidden away out of the worst of the frost. Another of the browns, the speckled wood has three overlapping generations so can be seen from late March to early November, it can also over-winter as ether a caterpillar or a pupa.
In other news, I saw the larger of the lapwing chicks today from tern hide and it must be getting close to fledging now, as is the one remaining oystercatcher chick. The three smaller lapwing chicks seem to have been reduced to two, but they at still growing well. Out on the rafts most of the common tern eggs have now hatched and generally they seem to be in broods of three, with lots of small fish being brought in, so they are growing fast. Today many of the chicks were using the shelters to get out of the strong sunshine, over-heating can be a real problem for small chicks, so shade is important.
