Yet another picture from my old archives of the year 2006.

Blister Beetles are beetles (Coleoptera) of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. There are approximately 7,500 known species worldwide. Many are conspicuous and some aposematically colored, announcing their toxicity to would-be predators.

Description

Cantharidin is a poisonous chemical that causes blistering of the skin. Cantharidin is used medically to remove warts[2] and is collected for this purpose from species of the genera Mylabris and Lytta, especially Lytta vesicatoria, better known as "Spanish fly".

Blister beetles are hypermetamorphic, going through several larval stages, the first of which is typically a mobile triungulin. The larvae are insectivorous, mainly attacking bees, though a few feed on grasshopper eggs; while sometimes considered parasitoids, it appears that in general, the meloid larva consumes the immature host along with its provisions, and can often survive on the provisions alone, thus they are not obligatory parasitoids but rather food parasites that are facultatively parasitoid, or simply predatory. The adults sometimes feed on flowers and leaves of plants of such diverse families like Amaranthaceae, Asteraceae, Fabaceae, and Solanaceae.

Hello Ram,
Happy to be your neighbour again:-). A species which I know well now, especially recalling your former shots of this beetle. Well chosen framing, the picture however seems to be a tiny overexposed on my screen.I see that you dig in your archives too. We had very windy weather for weeks now and a good shot of insects is almost impossible :-(
But next days should be better. Let's hope.
Herzlich grüsst
Anne
