I was wondering what the maximum temperature that D. tityus larvae can be raised in. I was also wondering do higher temperatures lead to shorter development time? I have read it causes the lifespan to shorten, but does it also make the larvae go to maturity quicker? Are there conditions that are known to speed up development time or to slow development time?
IDing larval instars is still pretty foreign to me. L1 especially messes with me now that I have hatchling D tityus, as their head capsule seems to grow several times its original size during the first week or two, and I've been under the impression that the head capsule size should be a constant during each instar (except immediately after a molt). I checked on this bitey brat this morning, and it's much larger than last time I checked. Unfortunately, I did not previously measure its head, but currently the head capsule is measuring approximately 6.09mm wide. It's about 4-5 weeks since hatching. Is L2 a safe conclusion here? Is there some general guideline to head capsule sizes at each instar?
This is the only D. tityus I have ever found in FL. I found him back around February outside of East Orlando. Hes been growing much quicker than all of my other D. tityus larvae. All of my other D. tityus larvae are between 16-22 grams but this big boy just pushed 27 grams not too long ago. I hope he will get a little bigger before he pupates. I never feed any special supplements to my larvae. Only decayed leaves and wood that is collected locally. It will be interesting to see how big he will be once he becomes an adult. Has anyone else raised any huge D. tityus before? Here's a Comparison pic of the 27 gram larva next to one that is 17 grams
