D.Intermedia without dew??

[powersensor]

I received a drosera (D.intermedia) from bactrus mid of last month. The plant is placed in bright (not excessively bright) but cool area without direct sunlight and is in water tray. The plant was doing fine until a few days ago it looses its dew.

Is something wrong with that plant? or is it going into some sort of dormancy? I am thinking of covering the plant with transparent plastic container to increase the humidity and hope that it recovers. Any advice on what might have gone wrong?

This was how the plant look like a few weeks ago
