Green Tortoise Beetle
A broadly oval, flattened beetle that is bright green in life, with transparent margins around the pronotum and elytra. It closely resembles a tiny green shield when viewed from above.
Did You Know?
The green coloring fades rapidly after death, turning dull brown in preserved specimens, which is why museum collections do not reflect its living beauty.
Small Brown Stonefly
A very common small brown stonefly found in a wide range of freshwater habitats across Europe. It is one of the most tolerant stoneflies to mild pollution.
Did You Know?
Unlike most stonefly species that require pristine water, this species can tolerate mildly enriched conditions, making it one of the last stoneflies found in degraded streams.
