Ladybugs are highly abundant throughout Saskatchewan this month as they prepare for hibernation, experts report.
Georgiana Antochi-Crihan, the entomologist for the City of Saskatoon, mentioned that ladybugs experience cycles of population booms and declines. She attributed the current surge in ladybugs to favorable conditions, particularly the availability of food sources.
These beneficial insects primarily feed on aphids, scale insects, mealybugs, and other pests. While some areas like Regina have not observed a significant increase in ladybug numbers, the city did experience a notable rise in aphids, which contribute to the survival of ladybugs.
In North Battleford, Vesna Fa of Midwest Food Resources noted a similar abundance of aphids, attracting ladybugs to the area. Fa emphasized the importance of preserving ladybugs as they are beneficial allies in controlling garden pests.
Celebrating the diversity of ladybug species in Saskatchewan, Candace Savage, from Wild About Saskatoon, highlighted the significance of creating habitats for both native and introduced ladybug species. Among the various ladybug species in the province, the seven-spotted lady beetle, recognizable by its seven spots, is one of the most common.
As ladybugs gather for hibernation this month, they can be seen congregating in warm locations around buildings. Antochi-Crihan explained that ladybugs have natural mechanisms, such as antifreeze compounds, to survive the harsh winter conditions in the prairies.
The expected large numbers of ladybugs emerging from hibernation in the coming spring indicate their resilience and vital role in the ecosystem.
