Scientific name: Urocerus gigas
Size: Up to 40mm
Distribution: Found throughout the U.K.
Months seen: May to October
Habitat: Usually found in or near coniferous woods
Food: The larvae feed on dead wood
Special features: Great Wood Wasps are often mistaken for Hornets because they look similar to a wasp but considerably larger.
They're sometimes called 'Giant Horntails' for obvious reasons. The female Great Wood Wasp has a long pointed tube at the back of her body, and this is usually mistaken for a stinging organ. In fact it's an ovipositor, which she uses to lay her eggs in the trunks of coniferous trees. Despite their slightly fearsome appearance, these insects are quite harmless.
