If you like invertebrates (and who doesn’t?) check out the Circus of the Spineless at Burning Silo.
I take a casual interest in insects and other invertebrates, but one thing you quickly realise is that they’re really hard. I first really appreciated this when, quite pleased with myself for recognising something as a ‘scorpionfly’, I tried to look it up in a book and discovered there are something like 28 species just of scorpionflies in the UK. And that’s relatively modest compared to the beetles and things. So I mainly stick to birds.
Since I’m on natural history, check out the dioramas at Pruned; it’s worth clicking through the links in that post as well.
