Abstract

People often claim that they observe an increased amount of insect activity after rain.
Some articles suggest that water accumulation in the soil forces insects to leave the ground
which increases insect activity. Others state that a number of insects prefer a humid
environment and therefore are more active after rain. However, there is no scientific evidence
to support the observation. In this experiment, we tried to validate the above statement by
examining whether there was a significant difference between the number of insects observed
on sunny days compared to that observed on cloudy days after rain. We collected one set of
data from a grass field and another from a soil land under a maple tree. For each location, we
recorded the number of insects observed in two types of weather six times in pairs. The
analyzed data from both locations suggested an insignificant difference between the number
of insects observed in the two weathers. The observed increase in insect activity after rain
could be a misjudgement due to a higher frequency of insect appearance. Overall, we did not
have enough evidence to conclude that there is higher insect activity observed after rain
