Arrivals

cydia amplana by Bob Chapman

Although there has not been much sign of migrating birds at Blashford Lakes so far, there have been some insect arrivals. The birds at this time of the year are returning from breeding to the north, the insects, by contrast, are arriving from the south. It seems likely that there will be many more in the days to come as the high pressure builds back and temperatures rise again.

So far we have recorded a couple of lesser emperor dragonflies, but no southernmigrant hawker as yet, but I am hopeful that someone will spot one somewhere on the reserve soon. The other migrant so far have all been moths. This morning the traps had silver Yrush veneerdiamond-backed mothdark sword-grassCydia amplanaand Yponomeuta sedella, all probably freshly arrived from the south.

Cydia amplana, a migrant Tortrix moth that seems to be getting more frequently recorded each year.

Yponomeuta sedella, this could be a migrant or a scarce local resident, it feeds on Sedum species, mainly the larger ones such as orpine, which does not grow at Blashford.

Perhaps oddly there have been very few migrant butterflies this summer, just a few painted lady and those several weeks ago now. It has also been a very lean year for humming-bird hawk-moth and convolvulus hawk-moth so far, but maybe numbers will pick up.

Just as I wrote the above I heard a buzzing sound at the window, only to find a humming-bird hawk-moth trapped inside the house!!! I have just successfully released it into the great outdoors to continue heading north.

I wonder what tomorrow will bring…………
