Quick Answer
Insects that indicate approaching rain include crickets, grasshoppers, and cicadas, which are known to alter their behavior in anticipation of changing weather conditions.
Anticipating Rain with Insects
Crickets, specifically the house cricket and the field cricket, are sensitive to humidity and temperature changes. When rain is approaching, crickets will often begin to chirp more frequently, usually 2-3 minutes after the first drop in temperature.
Insect Behavior and Weather Patterns
Grasshoppers, particularly the desert locust, are also affected by changing weather patterns. Their behavior becomes more erratic and agitated when rain is near. Observe the grasshopper’s behavior by watching for the following signs: increased jumping, rapid wing movement, and a change in feeding patterns.
Cicada Rain Indicators
Cicadas, particularly the periodical cicada, have a unique life cycle that is influenced by weather patterns. When cicadas are preparing for the onset of rain, they will often begin to emerge from their burrows 1-3 days before the rain. By observing cicada behavior, you can anticipate the approach of rain and prepare accordingly.
