Before 1990 Brimstones (G rhamni, citroenvlinder) would be more abundant in summer than in spring, but this has shifted over time. The only explanation I can think of is that they go into hibernation sooner after appearing in summer, maybe to avoid summer heat. Other ideas welcome. #vlindermaand

Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics
Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.
