Fun Bloody-nosed Beetle Facts For Kids
Gallery
Timarcha tenebricosa, with the common name bloody-nosed beetles, is one of the most commonly found leaf beetles that are endemic to Europe. Their common name refers to its ability to produce a bright blood-like haemolymph when feeling threatened by its predators.
This defensive behavior ensures that predators cannot cause any harm to them. The blood-red fluid is foul-smelling and is produced by rupturing the thin membrane inside the beetle's mouth when they feel scared or threatened. The fluid comes out in large drops and is extremely pungent.
This species has a black body with a metallic blue sheen. Their body is curved and their antennae are well-segmented. These beetles can be found in grassland regions and hedgerows.
They are monophagous and feed on tender leaves and stems of bedstraws. This species is harmless to humans but is messy to handle. Their reflex bleeding phenomenon makes them a very intriguing insect to read about.
