This generation's looking quite secure, some excess too! 



The ones in Miami are Ignelater havaniensis, very similar in shape and size as these south american cousin but no one has cultured them yetThese are native to Florida (or a similar species) and I used to see them (and catch them) in Miami. I never tired to keep them.
There used to be so many, it would look like Christmas lights in the trees. Over the years less and less would show up. I wonder if they can still be found out there anymore . . .
Larvae are predatory and will feed on dog food and live invertebrates. Adults feed on fruits.I saw these when I was in Costa Rica! So cool! What do the larvae eat?
Like @Lucanus said, those are probably Ignelater havenensis, nice find, been wanting to try my hand at culturing that species... Should be identical in care to Pyrophorus, so far the two Deilelater spp. I got from @Lucanus have been at least.These are native to Florida (or a similar species) and I used to see them (and catch them) in Miami. I never tired to keep them.
