Butterflies: April 2017
11 species were seen on the Estate in the best day of the year for species diversity. The first two Common Blues of the year were spotted in Middle Field whilst a Holly Blue at the Obs was only the second on the Estate so far this year.
This week’s BMS transect walk, carried out in watery sun and, if the forecasters are correct, just ahead of an imminent return to winter, would not have broken any records for numbers, but did include our first Small Heaths of the year.
In view of the early nature of the season so far, the appearance of the first Small Copper of spring in the Oasis field was conspicuously late, while two Painted Ladies were found in the Whitehouse in the afternoon.
The first Painted Lady of spring was nectaring in the Oasis and a few Red Admirals were scattered about, hinting at some immigration.
A scarce species here, a Brimstone was seen along the North Stream.
The start to the 2017 BMS transect year confirmed the early start to the season with a count of 16 butterflies; a record Week 1 count in the 11 years of recording.
