Wild Roseland – March 2017

There are thought to be approximately 160,000 species of moth worldwide, with over 2500 species having been recorded in the British Isles. Carol Hughes has been recording and photographing some of the many species to be found right here in the Roseland.

Moths belong to a group of insects which include the butterflies, the Order Lepidoptera. Fossils of moths have been found that may be 190 million years old, showing that moths evolved long before butterflies.

Oak Eggar (Lasiocampa quercus)

Most moths are nocturnal but you will see some in the day time. They have the same life cycle as butterflies; eggs, caterpillar, pupa, adult. Caterpillars, like their adult, form vary in size and colour.

So far at Ruan I have recorded 38 different moths: mostly ones that I have found in the kitchen after the door has been left open in the evening. Several have been recorded while out walking including Oak Eggar (Lasiocampa quercus), which at first I thought was a butterfly. It was constantly flitting all over the road and took a while to get a clear photograph of.

Twenty-plume (Alucita hexadactyla)

My most recent addition is Twenty-plume (Alucita hexadactyla), found in the kitchen. Measuring only 1.5 cm it is a micro moth. Its wings are made up of six ‘plumes’ or small feathers – so its common name is a bit mis-leading – and is very beautiful.

If you are out walking, the most commonmoth you are likely to see is the Common Carpet (Epirrhoe alternata).

In the garden, if you have Valerian or Buddleja you may be lucky enough to see the Hummingbird Hawk moth (Macroglossum stellatarum), as it flits about between the clusters of nectar-rich flowers. 

Primula vulgaris

What to look out for this month in the Roseland – colourful flowers

Primrose season is already upon us. Look out for sprawling patches of these cheerily beautiful flowers (Primula vulgaris) brightening shady places under our Cornish hedges.

Not all of them are yellow either, some being naturally pink forms. Look out too for the bright green foliage and nodding purple flowers of Sweet violet (Viola odorata) wafting their soft scent on the breeze; a sure sign that spring has arrived.

He will lead a walk around his farm to show what he has done and achieved for wildlife, and the range of farmland and coastal habitats he manages.

Led by Chris Townsend.

Seaweed identification walk and practical session as part of the Natural History Museum and Marine Conservation Society’s annual Big Seaweed Search around the country, to gather data on the occurrence and trends of seaweeds. (Numbers limited to 12 so booking required)

Event Success!

In January we had a presentation from Niki Clear of Cornwall Wildlife Trust on the work of the Environmental Records Centre for Cornwall and Isles of Scilly (ERCCIS) and their online wildlife recording system (ORKS – Online Recording Kernow and Scilly). This fascinating talk was well attended by 28, many of whom brought their laptops and tablets for live practice on the ORKS system.

Picture and species of the month

These are the catkins of Alder (Alnus glutinosa), one of our British native trees, showing that spring is surely underway. Alder is a member of the Betulaceae family, which includes the birches. Alder trees actively improve their surrounding soil fertitlity through their symbiotic relationship with a soil bacterium, Frankia alni. The bacterium helps fix nitrogen from the air into the tree’s root nodules. The tree feeds on the nitrogen nutrients, while sharing the sugars it produced from photosynthesis with the bacterium. You can find out more about the importance of Alder to wildlife and humans here:
