Weak or straggly traps or poor trap function prompt a light review. Scorch on leaves against hot glass points to excessive heat or a sudden intensity change.
Light needs for Dionaea muscipula
Give Dionaea muscipula the brightest safe position you can, up to full sun after acclimation. Strong light can deepen trap color, but hot glass and sudden exposure can scorch it.

Check the light reaching the leaves
Best position and light
Use the brightest safe position available, up to full sun after acclimation. Partial shade is also listed for this species, but full-sun hours are not an indoor light-dose requirement.
Use a bright windowsill or similarly bright position, but protect leaves from excessive heat through glass and avoid abrupt exposure changes.
Recheck the same position through the year
Seasonal light changes
Keep light strong during active growth and provide the cooler winter rest described for Venus flytraps rather than leaving the plant warm and dim year-round.
Inspect the plant before moving it
Signs the light may be wrong
Some light thresholds remain unknown
