Final-year projects already underway with our School of Biosciences: i) using a bioreactor to investigate how global change processes affect algal lipids ii) effects of misconnected sewers and micro pollutants on a small urban stream

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?

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?

Green-brindled Crescent - so fresh I’m guessing it’s probably from on of our garden Hawthorns
Allophyes oxyacanthae
Allophyes: changing in character (there are two colour morphs)
oxyacanthae: from Hawthorn or ‘sharp thorn’

The 2nd Clifden Nonpareil for the Cardiff garden - last caught 8/9/23. The expansion in range and numbers looks rapid: not even indexed in Glam Moths (2014). Bluesky had 33 UK mentions in the last 7 days alone on walls, attics and traps including Bridgend and Whitby
