The crumbling cliffs and resulting landslip habitat of our south-west coast is perhaps a stronghold in Southern England of two parasitic species of solitary bees. Firstly the large and flightless Oil Beetle, Meloe proscarabaeus. Its lifestyle is referred to in my earlier post of the 30th April 2017 entitled Oil Beetles.The second species is the Dotted Bee-fly Bombylius discolor. This bee-fly also has a strong connection with solitary bees and wasps. Its lifecycle is explained in my post of the 1st April 2016 Bombylius discolor.
Both these were encountered yesterday on the cliffs.
