Beaver wetlands create a buzz and a flutter for pollinators
Our results show that beaver wetlands boost hoverfly richness/abundance, butterfly abundance and diversify foraging resources for pollinators while comparing favourably with human-created ponds for o...

November Moths: Epirrita sp./spp.
‘Epirrita’ refers to the wavy markings resembling flow patterns on the surface of a river - according to Jacob Hübner who first named this moth (and many others).

Angle Shades from last night’s trap
Phlogophora meticulosa
Phlogophora: light bearing, and a throwback to when this moth and Small Angle Shades (with bright yellow spots) were in the same genus
meticulosa: fearful, timorous. From the posture or quivering pre-flight wings?

Moths need darkness to thrive 🖤
But globally, light pollution is increasing by 10% a year, and these vital nocturnal pollinators need our help.

Box Tree Moths first turned up here in Cyncoed (Cardiff) in 2021 but numbers in the garden trap have dropped since peaking in 2023. Caught here from June to late October - peaking in early September - with a hint of two generations?
