Ladybugs are highly prevalent throughout Saskatchewan this month as they prepare for hibernation, experts revealed.
Georgiana Antochi-Crihan, the entomologist for the City of Saskatoon, noted that ladybugs undergo cyclical fluctuations, and the current period seems to be experiencing a surge in ladybug numbers. She emphasized the importance of considering the small details in understanding this phenomenon, attributing it largely to the availability of food for the ladybugs.
These beneficial insects primarily feed on aphids, scale insects, mealybugs, and other pests commonly found in agriculture. While Ashley Thompson, the manager of parks technical services for the City of Regina, did not observe a significant increase in ladybugs in Regina, she highlighted a notable rise in aphid populations, which contribute to the thriving environment for ladybugs.
Vesna Fa from North Battleford also witnessed a high presence of aphids this past summer, attracting ladybugs to her garden. Fa, the executive director of Midwest Food Resources, advocated for preserving ladybugs as they are beneficial allies in controlling garden pests.
Candace Savage, chair of Wild About Saskatoon, emphasized the importance of celebrating the diverse ladybug population in the province for their ecological contributions. With around 75 ladybug species in Saskatchewan, including both native and introduced varieties, it is crucial to support their habitats and the biodiversity they enhance.
As ladybugs prepare for hibernation during the warmer days of this month, they gather in clusters near buildings for shelter. To endure the harsh prairie winter, ladybugs produce internal compounds, including antifreeze agents, to survive the freezing temperatures. The forthcoming spring is expected to see a resurgence of ladybugs as they emerge from hibernation.
