Yes, that often happens when a Flytrap used to more humid conditions experiences hotter, dryer conditions, and it's nothing to worry about to much. Venus Flytraps will adjust to lower humidity and more sunlight, but occasionally a newly emerging trap tip will dry and darken.
It helps in the long run not to overwater the plants. When watered too much, Venus Flytraps can grow faster, but the leaves are thinner and weaker, more fragile and susceptible to such things as you mentioned. So it's a good idea to water thoroughly but conservatively, allowing the medium to dry substantially before watering again, unless the Flytrap wilts terribly, in which case the process of going from overwatering to conservative watering will have to occur more slowly, but is still a good idea, in my opinion.
