Update on the edible beetles – more reports needed!

May 29, 2010

By contacting Dr Mary Liz Jameson, Wichita State University, USA, we got a confirmation that the edible beetles reported here two days ago, are Peltonotus nasutus (Scarabaeidae). The male of this species has a small hump, like an immature horn of a calf, at the end of the shield covering the mouthparts (clypeus). The male of the other species also reported from AmorphophallusP. morio, does not have this character. Males are distinguished from females by the large fore legs used during mating.

Apparently the habit of eating them has never been published in entomological literature. We therefore ask our readers if you can share additional observations. We try to:

1. Ascertain where in Thailand, and the world, people eat these particular Peltonotus beetles. 

2. Are there ethnological studies mentioning these beetles?

3. Has anyone ever seen these beetles on carrion, or are they specialised in pollinating Amorphophallus?

The beetles should be washed before frying.

    I found some information about this beetle on Thai website:

    they said that the beetle named Peltonotus nasutus , ~ 2 cm, feed on flower of Amorphophallus paeoniifolius and being its pollinator , besides this beetles are edible…never seen report this beetle on carrion!

    very interesting!!

      Yes, that looks like the beetle we found too. I have mailed a male Peltonotus for an ID by Dr Jameson. There could be several species involved. Dr Jameson believes this is a specific Amorphophallus pollinator too, i.e. not a carrion visitor as I feared.

      Thanks, Eric Danell
