Confidence: It might be this.
Notes: This is certainly a geometrid. The resting posture is not familiar: I wonder if it is not fully at rest. It is also rubbed on the inner angle of the left forewing. The only other reasonable alternatives could think of were 1)Early Tooth-striped, Trichopteryx carpinata, and 2. a semi-melanic Engrailed, Ectropis bistortata, though I think this would normally be over 8 mm body-length.
