The Food Chain..

One thing they teach in school biology is the concept of food chains and food webs – the links that show interdependence of organisms based on the foods they eat. The photo below shows one such food chain starting with the rose (the producer) providing nourishment in the form of sap for aphids. In turn aphids are milked by ants for honeydew, a secretion that aphids produce.  Ants are also known to “farm” aphids storing their eggs over winter and then carrying newly hatched aphids to emerging plant shoots in spring (called a mutualistic relationship).

A Demoiselle (not in distress) fly

Earlier this summer, I spotted this beautiful banded demoiselle fly (female) perched on a flower bud. And it just so happened that I had my camera with macro lens! Some results are below.

There are, according to this handy website, only two species of demoiselles in the United Kingdom, of which I have now photographed one. The other I have seen on occasion in the west country but never been close enough to take a decent photograph. Demoiselles belong to the same family as the dragonflies but are more closely related to the damselflies.
