Goliathus Posted April 27, 2021 Report Share Posted April 27, 2021 A couple of nice Dynastes tityus males that I had emerge today - huge size, and with great horn development; some of the best examples of this species that I've ever produced. They took around 14 months to go from eggs to adult emergence - Quote Link to comment Share on other sites More sharing options...

Dynastes TItyus hunter Posted April 28, 2021 Report Share Posted April 28, 2021 WOW. Is that the record? Quote Link to comment Share on other sites More sharing options...
Goliathus Posted April 28, 2021 Author Report Share Posted April 28, 2021 I think I might have missed the record by less than 2 mm. I've seen a super-exceptional 70.75 mm tityus, but don't know if this species is able to exceed that. In any case, anything between 65-70 mm can be considered an exceptional size for tityus. Over the years, I've produced many 60-65 mm specimens, but the 66-69 mm range have been considerably fewer in number. This seems to be the way it is with a lot of beetle species; there's an "average" maximum size, and then anything beyond that only constitutes a quite small percentage of a population. This happens both in the wild and in captive rearing. Quote Link to comment Share on other sites More sharing options...

They look like 25 years of selective breeding (1995 yellow stock) and a much better breeder than I (my biggest of that stock was 67).

markjfisher Posted June 19, 2021 Report Share Posted June 19, 2021 These are absolutely incredible! When you get individuals of this size, what do you do with them? Do you keep them as breeding stock, or "preserve" them as fresh as possible? Absolutely phenomenal job here. Quote Link to comment Share on other sites More sharing options...

I'll occasionally save a really exceptional one (usually males) as a preserved specimen, but generally, not until after they've mated a few times. That way, I can keep the best genes flowing in the culture, and get some nice specimens as well. Quote Link to comment Share on other sites More sharing options...
