Some interesting finds on this week’s recording walk at the Tarn. The bright sunny day had brought out lots of insects.

4 species of Butterfly were seen including the first Blue of the year, a single Holly Blue along with Small White, Orange Tip and Speckled Wood.

A couple of other interesting finds were a number of Bee-flys (Bombylius Major) and a hover-fly which is a Bumblebee mimic (Eristalis Inricarius). Thanks to the Insect facebook community for rapidly confirming ID  on these.

The usual resident birds were present. The Coot are nesting and one pair of Greylag Geese already has 5 goslings. One visitor stopped me to say he had seen 2 Carp in the water at the western end of the Lake, which must be another good sign that water quality is improving and this may be related to a Grey Heron fishing in the shallows at the eastern end, although he is probably after smaller fish.

On this week’s insect survey I came across this creature. At first I thought it was a bee, but on close examination the head and the wing pattern were clearly not of a bee. Then I saw a post on facebook about the Bee Fly, a family which I had not encountered before. I think this is an example of Bombylius Major, it certainly looks very like the pictures I have found.

Bee Flies feed on nectar and pollen and are important pollenators. The larva feed on other insects, Although there are a large number of species (c4500 have so far been identified), they are not well studied and much is still unknown about their biology.

The mouth parts have become specially adapted for feeding on pollen in much the same way as that of a hummingbird. The length varies with those of the Bombyliinae approx four times the length of the head. The Wing venation is also of help in seperating the species.

The larva are buried in the sand and are parasitic on other flies and bees.
