← Nature & AnimalsWhich outcome commonly occurs when Monarch butterflies’ magnetic receptors are disrupted during migration?
A)Arrested development of larval stages
B)Complete halt in eastward flight path
C)Sporadic deviation from southerly paths✓
D)Inability of offspring to overwinter
💡 Explanation
Minor navigational errors occur because disruption of the magnetic compass affects the sensory mechanism which aids their migration south; therefore, deviation happens rather than a full stop because other navigation methods supplement the impaired magnetic sense, but do not completely compensate.
