Blister Beetle: Mylabris pustulata

Location: Karnataka, India

Season: Winter, Novenmber

Order: Coleoptera 

Family: Meloidae 

Mylabris pustulata

We have a field full of Pigeon Peas (Toor Dal) growing in our farm in rural Bangalore. There are a lot of these beetles floating about from flower to flower. They are huge and it looks like the wings struggle to keep them in flight. They are very pretty to watch but they don't do good for the crop.

As the name Blister Beetle and Pustulata suggest, the exudate from these beetles can cause blisters on the human skin.

Correction of identfication: This beetle looks like a Black Pintail Beetle - Tomoxioda aterrima
Originally Identified as Tumbling Flower Beetle


A tiny black insect with shimmering gold and silver bands was found on the African Daisy flower. It is the Tumbling Flower Beetle Black Pintail Beetle; Tomoxioda aterrima. The pintail, which is a projection of the abdomen and its arched back are prominent features. What made me think it was a beetle is the filiformis antennae (present in certain beetles and cockroaches). The behaviour of the beetle confirmed my diagnosis. It rolled itself up with its pointy tail, fell upside down - played dead, and just waited there for the predator (me with my camera pointed close to it) to go away. It leapt and jumped out to disappear from my sight. The tumbling action got me worried for the little one but the fact that this action is a defence mechanism put my mind at ease. It must be okay somewhere.
