Ladybugs are abundant in Saskatchewan this month as they prepare for hibernation, experts say. Georgiana Antochi-Crihan, the City of Saskatoon’s entomologist, mentioned that ladybug populations follow cycles based on food availability. Ladybugs primarily feed on aphids, scale insects, and mealybugs. While Regina has not experienced a significant increase in ladybugs this year, Ashley Thompson noted a high aphid population in the city, which supports the survival of ladybugs.
In North Battleford, Vesna Fa observed a similar abundance of aphids during the summer, attracting ladybugs to the area. Fa, from Midwest Food Resources, emphasized the importance of preserving ladybugs as they are beneficial insects. Candace Savage, Chair of Wild About Saskatoon, highlighted the significance of celebrating Saskatchewan’s diverse ladybug species and providing suitable habitats for these insects.
As ladybugs prepare for winter hibernation, they gather in warm locations like building sides in Regina. Antochi-Crihan explained that ladybugs produce internal compounds, including antifreeze, to survive the cold prairie temperatures. The ladybug population is expected to increase significantly next spring as they emerge from hibernation.
