30 Days Wild – Day 9

The moth trap this morning did not have a lot of moths, although there was the first large yellow underwing of the year, this is one of the commonest moths in the trap throughout late summer and the autumn.

As well as a couple of common chafer beetles there was also a great diving beetle in the trap.

Diving beetles can fly between ponds and do so a lot as anyone who has made a garden pond will know, they can attract beetles with in hours. Fish are not so mobile, although they are often said to get moved as eggs attached to the legs of ducks there is rather little evidence for this. Overwhelmingly they are moved by people or move between sites during flood events. Two common species in the lakes on the reserve are rudd and perch, both in the picture below.

Fish are prey for some birds such as kingfisher and heron, but also predators, taking smaller fish and lots of insects. So the larval stages of dragonflies, although voracious predators themselves have to be skilled at avoiding fish throughout their nymphal stage. So it is perhaps a surprise that so many dragon and damselflies survive to adulthood. Today I added another species to this years list when I saw my first scarce chaser of the year.

Scarce chaser used to be a rare species of larger rivers, but in recent years it has spread and now exploits standing waters as well, just like the commoner broad-bodied chaser, although that specie soften uses small ponds too.

I had been wondering where out bee orchids had got to, with lots of pictures of them flowering elsewhere I wondered if we had lost ours, but no, they were just a bit later coming into flower.
