Cavenham Heath is part of the Brecks. Much of that habitat has now been lost so Cavenham is a remnant of that particular habitat of heathland and acid grassland. It is an important site and is designated a National Nature Reserve and a Site of Special Scientific Interest. The heath is next to the River Lark where it becomes wet grassland and fen and is surrounded by Birch woodland. It is managed by Natural England.
Late September probably isn't the best time to visit although there are apparently post-breeding flocks of Stone Curlews. Needless to say I didn't see these. I did see Green Woodpecker, Tree Pipit and loads of corvids.
The walk was very pleasant in the sunshine with a few insects venturing out into the cooling breeze. Lots of Common Darters were about including this female.
A Small Copper plus the odd Large White were seen flitting about on the track edges.
This Devil's Coach horse beetle was seen examining an over ripe dog turd, off which there were many (turds not beetles). Dog walkers that leave their pet's produce on the ground (or in little bags hanging from trees) really piss me off. Not only is it a walking hazard but I guess it also adds nutrients to areas that may not traditionally have many.
Roesel's Bush-crickets were apparent from their low soft sung in patches of longer grass. I've been noticing this song at several places recently.
I saw a couple of these sand wasps in the sandy edges to the tracks. Given I was in the Brecks this is most likely to be Kirby's Sand Wasp Podalonia affinis although hirsuta is a remote possibility.
On my way back to the car I noticed a late Volucella zonaria flying around a young oak and managed a few shots before it flew off. Always nice to see and I'm always amazed at what a whopper these are.
