The Common Tern has become an increasingly common sight on inland waterways. It is not uncommon to see one fishing on the River Stort.

In Hatfield Forest there is a nest raft which the Terns try to use but they are subject to predation and competition by ducks and geese which also try and get onto the raft!

The Silver Washed Fritillary is a success story in our region. This pair was photographed in Hatfield Forest where it has returned in recent years.

The butterfly is quite specific in needing Dog Violet as a food plant for the caterpillars and then old tree stumps nearby in which they overwinter before completing their development the following year.

The warm weather this year must have been good for snakes.

This Grass Snake was seen hunting an old kitchen garden wall from which it had flushed a small Bank Vole.

Moss of the month is Marchantia polymorpha which is more correctly referred to as a liverwort.

This plant is often found as a ‘weed’ in greenhouses and is more often seen as the flattened plant body or ‘thallus’.

This photograph shows the umbrella-shaped fruiting bodies and the plant growing in a typical path side situation, traditionally the light to be in association with cinder paths.


This large and spectacular caterpillar is often found feeding prominently on the plant of the same name.

It seems to have some defence against parasites which would lay their eggs inside it, instead although being very obvious, it does not seem to suffer so much in this way.

The adult moth is nowhere near as spectacular as the caterpillar being quite large but brown.
