Sounds like a highly satisfying day out, Mark. The numbers Neil H was talking about would be incredible in a location where PBF was long established, let alone somewhere that has only recently been managed for them.essexbuzzard wrote:..It’s been a couple of years since I’ve seen the Pearl Bordered Fritillary. So, with a last minute change of plan, I got my chance on Monday to head down to Rewel wood in Sussex. It was nice to meet several other enthusiasts on the main east-west ride, including our very own Neil Hulme, who was doing a very successful timed count of the PBF population. But we all got to see many of these lovely spring Fritillaries!
That’s really surprising, Mark, as I was only telling my neighbour the other day that I’d never seen so much of it round my way. I wonder whether the hotter, drier conditions in the SE during last year’s heatwave played a role?Here, the main caterpillar foodplant is garlic mustard. However, being an annual, it’s appearance each year is highly variable, depending on a fresh crop of new seedlings, unlike cuckoo flowers, whose population is more stable. Flowering mustard plants are scarce this year-certainly most of the seedlings in my garden shrivelled in last years heatwave-so it’s possible we will see a temporary decline in Orange Tip numbers next spring.
