Trilobite beetle and lookalike

I finally found my first Trilobite beetle. Well, actually, it was found by my friend, David Fischer. Anyway, when I saw it, I thought it was just another firefly larva (Lampyridae), just like the one I found in Sg Krau, Raub about a month ago!

So here it is, the magnificent Trilobite beetle, natural light. Found in Selangor, Malaysia.

A different type of Trilobite found in Sarawak, Borneo.




And now the Trilobite look-alike that got me excited for the wrong reason:D. As mentioned, I found this about a month ago in Sg Krau Forest Reserve, Raub.


It's actually a firefly larva (Lampyridae)




Well, the next time I come across another one of these, I think I will just turn it over to check if there is any light emitting organ on the tip of the abdomen!

More tropical beetles here.
