19months old and no eggs :D

Temperature for sure plays a part in the reproductive cycle.
When i place here pardalis outside in summer, temperature is on average lower as would be inside the house.
Most females then do not want to mate anymore, although they were ready to made when inside, placing them outside, makes them go angry at any approaching male (sofar not any produced then a clutch by itself) placing them inside the house, generally makes them wanna mate again within a few weeks.
I think the food does too.

Sometimes i have kept multiple females in the same cage, and then still it varies, with the reproduction. 1 makes a clutch by itself, while the other does not, while all factors influencing in principle are the same...

Reproduction is influenced by hormones, as does stress also influence hormone level.
On a few occasions with Calyptratus, when moving them to another enclosure, just around the moment adult coloration comes around, they made a clutch by them self, can be coincidence, can be not...

Often was told in the past that they might die making a clutch by themselves, which is also not the case if people still might think. (ofcourse one can die, but a mated female might also...) this mostly without substrate ofcourse in the cage, or any other issues might causing it.

On 1 of the females which made a clutch by itself, i hadn't noticed, and hardly had a substrate on the floor, it was less then 1 cm substrate. When i came home, the bottom glass of the cage was mainly visible, she had laid the eggs in a corner of the cage, and had put all the substrate on top of the eggs. She did wel lucky me...

For me Calyptratus, Pardalis and Lateralis can make unfertilized clutches by itself to be sure. Others i dont know.

How abouth the live bearing species, anyone ever there had an infertile clutch, without mating?

if they are live bearing... how would they produce infertile clutches, since they have live babies, not eggs...
 
They have follicles inside which you can sometimes see when they bear the young... more on 2nd...3rd clutch when not mated again.
These are then not fertilized. look like eggs without shell, yellow and very soft.

just wondering or anyone ever had this with a live bearing species...
 
What I have found during my 20+ years of experience is that some species like Senegals and Fischer's multis won't produce eggs without mating while others like panthers and veileds can produce clutches without having been mated (but don't always).

I had a female multituberculata produce a LARGE clutch of infertiles at 10 months of age. She was given 3 or 4 different egg laying sites/substrates and refused to use any until she was placed into a 32 gallon garbage can with a 70% peat/30% sand substrate. By the time she finally accepted this site, ( I don't know if it was the can or the subsrate composer that finally prompted her) she finally started a tunnel but she had become egg bound and didn't survive. But nontheless, she was never in contact with a male, but produced this clutch.

There was a thread here about it. https://www.chameleonforums.com/what-these-46663/

Money quote is from Chris Anderson. HERE
Jackson's give live birth but all that means is that they retain developing embryos inside uncalcified egg cases and the neonates "hatch" immediately at or following oviposition. Having a female jackson's drop a clutch of slugs (infertile eggs) has nothing to do with not being healthy or fed properly. They will drop infertile clutches without a male, just like egg laying chameleons lay infertile clutches, and chickens lay infertile eggs.
 
Thanks Eliza, so can happen in jacksons also.
I had once 3 jackson females upto age 4/5 years in a room with 1 male.
Never anything happened, babies nor slugs. (the male never wanted to mate)
 
You said.."Often was told in the past that they might die making a clutch by themselves, which is also not the case if people still might think."...I'm pretty sure the person who reported this had husbandry issues that would have caused the prolblem. I first heard that at the time that my first veiled was getting old enough to produce a clutch and I was very worried because I decided that it was not true and decided not to mate my female. She did fine....of course.
