Tardigrades have been found everywhere in Earth’s biosphere, from the highest mountaintops to the deepest sea and from tropical rainforests to the Antarctic. There are sure to be some, somewhere, in the reserve’s ponds, going quietly about their business.

Ecosystem engineers are organisms that modify their environment. They increase biodiversity by creating habitat for species other than themselves. The oak apple, caused by a tiny wasp called Biorhiza pallida, is just such an engineered environment.

Simon Tesler’s video of an otter hunting in the moat at Southwick Court is powerful evidence not only of Lambrok Stream’s biodiversity, but its importance as a wildlife corridor that runs from the River Biss right up through and beyond Southwick village.

Live Knight has sent in pictures of the reserve’s jays busy this week caching acorns.

Mail from Cheryl Cronnie with pictures of a kingfisher:
Hi there, I’d just like to share with you the kingfisher I spotted today at Southwick Country Park by the pond. I was over the moon as I had never seen one before.
Lovely! Thank you, Cheryl.

There are silk button galls on the underside of oak leaves all over the park.

There are hundreds of species of crane fly in this country and almost all of them go by the name of daddy long legs. The differences between species can be microscopically small but we think this specimen photographed in the reserve is either a common European crane fly (Tipula paludosa) or a marsh crane fly, (T. oleracea).
Most of our willow warblers will have left by now; they will be on their way to sub-Saharan Africa where they will spend their winter. Theirs is the longest journey undertaken by any of the park’s migratory birds. Why do such tiny birds fly so far and take such risks to do it?

There are several families of magpies in the reserve. This year’s crop are, as yet, short-tailed, loud- mouthed and clumsy, hanging out in gangs and still learning to fly properly. But, despite their dramatic black and white beauty, their reputation is poor.

One of the delights of September is a pristine, newly hatched, late brood small copper butterfly. This one was was photographed last week in the reserve by Clive Knight.

Collared doves (Streptopelia decaocto) bred in Britain for the first time in 1955, in Norfolk. Within 20 years they had colonised every county in the British Isles, and had even reached Shetland and the Outer Hebrides.

Keep a look out for hibernating amphibians as you tidy up your garden ready for winter. Frogs, toads and newts will find sheltered places to hibernate in hedge bottoms, compost heaps, under stones and in log piles and are best not disturbed. Take particular care if you are planning to clear out a pond: frogs and newts will sometimes overwinter in the mud at the bottom.

Cryptic colouration, is another name for camouflage, a defence strategy that creatures use to disguise their appearance, or to mask their location, their identity, or movement. It both allows prey to avoid predators, and predators to sneak up on prey.

During last week’s moth trapping in Village Green, Ian and Hugo identified an oak lutestring (Cymatophorima diluta), a UK Biodiversity Action Plan Priority Species, classified as scarce and local. This is the thirteenth BAP priority species of Lepidoptera identified in the reserve: the hard work we put into our woodland habitat is paying off!

The breeding season of the reserve’s nursery web spiders (Pisaura mirabilis) can extend well into September.

Usually we would welcome predators into the reserve; they are a sign of a healthy ecosystem. We have resident stoats and weasels, foxes and badgers and are happy to know that our ecosystem can support them. Domestic cats, like this one photographed early in the morning in the woods in Village Green, are a very different proposition.

A common field grasshopper (Chorthippus brunneus) photographed by Ian Bushell in the park this week. This is a species that thrives among fined-leaved grasses, a sure sign that our policy of reducing the fertility and thus widening the biodiversity of our fields is working.

This late in the year, there are few butterflies about but there is always a speckled wood (Pararge aegeriais) somewhere. Here is one on hawthorn berries photographed in September 2019 by DKG.
