A Record Breaking Day for Butterflies at Tidgrove Estate
We are delighted to share the results of the latest butterfly survey carried out by Andy Bolton, and what an incredible day it was.
An astonishing 20 species of butterfly were recorded during a single visit, almost one third of all Britain's butterfly species. This is believed to be the highest species tally ever recorded at Tidgrove in a single survey and is a wonderful testament to the habitats developing across the estate.
Some of the highlights included the beautiful Brown Argus, Small Copper and the tiny Small Blue, shown in the accompanying photographs, alongside impressive numbers of Meadow Browns, Marbled Whites, Small Skippers and Peacocks.
The survey also recorded Pyrausta purpuralis and the nationally localised micro moth Sitochroa palealis, which represents a new 10 kilometre square record. This is particularly exciting because Sitochroa palealis is closely associated with Wild Carrot, which now flourishes across Tidgrove's meadows. Its caterpillars feed within the flower heads, making this native wildflower an essential part of its life cycle. Often overlooked as just another wildflower, Wild Carrot is in fact one of our most valuable native plants, providing food and habitat for a remarkable range of insects.
These results do not happen by chance.
At Tidgrove Estate we are working to create a landscape where butterflies, bees, moths and other pollinators can thrive. By restoring species rich grassland, reducing unnecessary mowing, creating sunny meadow margins and encouraging native wildflowers to establish and set seed, we are providing food and habitat from spring through to autumn.
Many of the plants we are encouraging have a specific purpose. Kidney Vetch supports the Small Blue butterfly, while Wild Carrot, Knapweed, Field Scabious, Devil's Bit Scabious, Wild Marjoram, Red Clover and Oxeye Daisy provide valuable nectar for butterflies, bees and hoverflies. We have also been introducing Horseshoe Vetch, one of the defining plants of Britain's chalk grasslands and the sole larval foodplant of both the Chalkhill Blue and Adonis Blue butterflies. As these habitats continue to mature, we hope it will help support an even greater diversity of wildlife in the years to come.
Allowing these plants to complete their natural life cycle creates a healthier ecosystem that benefits everything from insects to birds and bats.
Seeing species such as the Brown Argus, Small Copper and Small Blue, together with the discovery of Sitochroa palealis, tells us these habitats are becoming richer and more diverse each year. It is an encouraging sign that the work being carried out across the estate is making a real difference.
Thank you Andrew Bolton for carrying out the survey and helping us monitor the remarkable wildlife that calls Tidgrove home.
