From the posture, it looks like it can belong to Geometridae (Larentiinae). But I haven't been able to find a species that has that particular color.
Definitely a moth; possible families are Pyralidae, Crambidae, or Thyrididae (Window-Winged Moths); the first two listed (Snout Moths) are less likely and would be eliminated if a photograph showing the front of the head were available and it turned out that the palps were not elongate and projecting.
