Large-legged Chalcid
A parasitoid wasp with conspicuously thickened hind femora used to brace itself while ovipositing. It attacks the pupae of tachinid flies and various Lepidoptera.
Did You Know?
Despite looking like it could jump powerfully, those thick hind legs are mainly used for gripping, not leaping.
Lesser Swallow Prominent Moth
A white moth very similar to the Swallow Prominent but with a thinner dark wedge mark and a clear white hindwing. It is associated with birch rather than poplar.
Did You Know?
It can be reliably separated from its close relative only by examining the width of the forewing wedge mark.
