Riverfly Survey in Toft

Toft Bourn Brook Group is carrying out surveys of the invertebrate species in the Brook according to the Riverfly rules and regulations for acquiring the samples and then counting the species found in the water. The species that are monitored include Mayflies, Olives, Stoneflies, Shrimps and  Caddis flies. Timed samples are taken and then examined for the Groups shown on the circular chart and the numbers of individuals counted. We also found very young Loach and American Crayfish plus Beetles, various Midge larvae and Pond Skaters etc

Marbled Whites, Privet Hawkmoth and Smaller Species

 For the first time, we had a couple of Marbled Whites on our Lavender bush and an impressive Privet Hawkmoth on the pear tree. Apart from these, there were lots of smaller insects to add to the garden list including this exquisite Ruby-tailed Wasp, which is a parasitoid on small stem and wood-nesting wasps, and very strange Hemipteran that feeds on small insects as well as plant buds and unripe fruits. 

Wild Flower Species in My Garden

It seemed a simple task on a free day to record what wild flowers are in bloom in my garden at the moment but I had underestimated how many species I would find and, even after over 60 years practising (yes it was a childhood obsession too), I still find getting attractive images of flowers in situ really difficult. Here are the species from my front garden which has herbaceous beds that are a mix of cultivated and wild species; I find these do really well together in maintaining a good ground cover and height  - essential in these dry conditions for invertebrate life.

Garden Spiders etc

Definitely to be too hot in Cambridgeshire to be outdoors photographing insects so these are the remainder from yesterday's garden hunt. The Flower Spider (Misuna) was deep inside a white rose with its prey while the Labyrinth spider has built an impressive den in the Acanthus. Blue-tailed, female immature Common Blue and male Azure Blue all competing for space around the pond. Favourite species the Figwort Sawfly. IDs on sheets at end of images.
