Bug Hunt: Millennium Wood Sunday 14th May

10 adults and 10 children met in Millennium Wood yesterday at 11a.m for a Big Bug Hunt. Using several techniques, knocking trees and observing what fell out on to a white sheet, netting flying insects over bramble and around oak, turning over log piles placed 2 years ago and generally checking leaves in sunny positions, we managed to create a good list of creatures, several new for parish records.
Without doubt, the highlight was finding 3 great crested newts under several logs. These were photographed and put back under the log. A superb find and one that has been reported to Natural England and Herts and Essex Wildlife Trust. With this find come several important rules for Millennium Wood but it must be noted that they were discovered in an area where we carried out improvement work in the winter of 2015/16. At that time I wished to improve the quality of the grassland by removing many poor and failing trees. By removing these, it meant light and rain could penetrate through the gaps in the woodland canopy and permit grasses and wild flowers to prosper. This work was further enhanced by the placement of many small log piles, under which, we discovered the newts. With the nearest pond some 400 yards away, it is now imperative that we find time and money to scrape out the original pond within the wood, add a quality liner and allow it to fill naturally with rain water. Once certain pond vegetation is added, this could be a superb opportunity to increase the newt population. Newts, as amphibians, only return to ponds to breed. The rest of the time they remain under log piles, hunting by night in grassy areas. Just the habitat we have provided, so all present were very excited by this excellent discovery.
The only other highlight was the flushing of a field mouse that scurried over several pairs of feet before hiding itself away. Another good record as their presence will encourage creatures towards the top of the food chain to move in, such as falcons, owls, foxes etc.

Amphibians :(Amphibia)

  • Great Crested newt  (Triturus cristatus)


As can be seen, the children did a great job of finding and potting creatures. We also tapped trees where we found caterpillars, mainly small green jobs from oak. Very difficult to identify these to specific species at this stage of their development. Consequently, I have potted them with plenty of leaf material and shall await their emergence as moths in high summer.
