Scarce Chaser
A medium-sized dragonfly where mature males develop a powdery blue abdomen. It is associated with clean, slow-flowing rivers with abundant marginal vegetation.
Did You Know?
Despite its name, the scarce chaser has become increasingly common in parts of Europe as water quality in rivers has improved.
Grain Aphid
A major pest of cereal crops in Europe and other temperate regions. It feeds on ears and leaves, reducing grain quality and transmitting barley yellow dwarf virus.
Did You Know?
Feeding on wheat ears during grain fill can reduce thousand-kernel weight by up to 20%.
