Is ladybugs swarming caused by global warming? After all, blaming climate change has become a popular thing to do nowadays.
As previously reported by The Inquisitr, the false widow spiders invasion in England was blamed on global warming.
Whether or not climate change could affect the crazy ants invasion was also speculated upon. The short of it is that the Tawdry crazy ants potentially could spread further into North America if it were to warm significantly. But other studies showed that ants in general were very sensitive to changes in temperature, so some scientists claim the general ant population may go down worldwide over the long term.
The ladybugs swarming all over Tennessee and the United States is raising the same questions over global warming. After all, the ladybugs swarming tends to be heaviest on warm days after a period of cooler weather. Since ladybugs are cold-blooded, during the winter they look for a warm place to bed down because they “basically shut down.” Folk lore even used to use ladybugs as an indicator of the weather.
Ladybugs swarms are limited by the air temperature. Generally, ladybugs swarming will not occur if the temperature is below 55 degrees Fahrenheit. So it’s possible warmer temperatures could play a factor in addition to land-use patterns.
This writer couldn’t find any scientist claiming global warming causes ladybugs swarming but in the past it has been claimed that climate change modified the colors of ladybugs. Black coloration tends to absorb more heat, which is optimal when the climate is cold. But the red coloration is better under global warming conditions because it’s easier to stay cool.
So, at the minimum, you can probably blame global warming on red ladybugs swarming, but not the black swarms.
