Writtle Wildlife Watch, June 2015

One of the joys of being a lecturer on the Conservation scheme here at Writtle is that you get to visit some wonderful places. And this year we took our first and second year students away for a week to the glorious area of the south coast, the New Forest. 

 

Maiden Castle, Dorchester

During what the Two Ronnies might have called ‘a packed programme’, (goodness, that makes me feel positively antediluvian!) we went all over Hampshire, Dorset and Wiltshire, visiting some great sites and talking to people working in a huge variety of Conservation jobs. 

 

For me though, the mini-highlight was on the Thursday when we stopped off to have a look at Maiden Castle, a magnificent Iron Age hillfort just south of Dorchester. Always impressive and giving beautiful views over the surrounding countryside, it is a particularly good spot for finding various birds such as Linnet, Skylark and Corn Bunting. And I thought that was all we were going to find but on the way down, student Jimmy suddenly stopped and said ‘Alan, what’s this funny beetle?’. 

 

Oil Beetle at Maiden Castle

Now, many species of insect are special but then there are others which really have the ‘wow’ factor. And Jimmy had found one of the latter – an Oil Beetle. 

 

Oil Beetles are peculiar and charming in equal measure. They are rather odd to look at, with an elongated body and narrow head, but have an exquisitely glossy sheen of black, violet and blue. They are totally reliant on solitary bees for the completion of their lifecycle, with the beetle larvae climbing flower-stems and waiting in flowers in order to hitch a ride on a passing bee. Back in the bee’s nest the larvae of the beetle feeds on its eggs, as well as the stores of nectar and pollen before emerging as an adult. 

 

We have lost three of our species in recent years and now only five are left. They favour flower-rich grasslands of the type found at Maiden Castle but sadly, we have lost many of these sites in recent decades, making an encounter with an Oil Beetle even more special.

 

Yes, we did see a Corn Bunting as we left but somehow it wasn’t the best wildlife sighting that day.
