All flytraps are going to hate higher temperatures, they just are not used to it. There are stronger cultivars and strains and sports of the flytrap, a prime example would be the green dragon from petflytrap, incredibly vigorous, by far my largest and most consistently robust flytrap...
I think however it is not that some need more or less of a condition, just that some take advantage of optimum conditions better, my green dragon does great in the same environment my dente do OK in... I think the dente benefits just as much from the conditions as the green dragon, but has a harder time showing it... (THey don't like my 100 degree summers very much.)
