## Taxonomy

- **Kingdom:** Animalia
- **Phylum:** Arthropoda
- **Class:** Insecta
- **Order:** Coleoptera
- **Family:** Meloidae
- **Genus:** Meloe

## Interesting facts

- Female oil beetles can lay thousands of tiny eggs in a single clutch!
- Its body produces a potent toxin called cantharidin, which is extremely dangerous!
- The larvae are tricksters, mimicking bees to lure males for a ride!
- These beetles are entirely flightless, relying on their legs to walk everywhere!

## Special abilities

- **Toxic Oil Defense:** Violet Oil Beetle can release a toxic, oily liquid from its leg joints because it contains cantharidin, which helps deter predators.
- **Bee Hitchhiker Larvae:** Violet Oil Beetle larvae can hitch a ride on bees because they are specially adapted to cling on, helping them find a bee nest for food.

## Measurements & details

- **Size:** 10-30 mm
- **Lifespan:** 30-60 days
- **Leg Count:** 6

## Diet & Feeding

Adults nibble on plants, while their clever larvae sneak into bee nests to eat.

- **Age differences:** Larvae called 'triungulins' attach to bees, feeding on their eggs, larvae, and stored pollen in the bee nest. Adults eat plant matter.
- **Primary Foods:** Buttercup leaves, Dandelion leaves, Nectar, Pollen
