Margined Calligrapher Syrphid Flies (Toxomerus marginatus) are widely distributed across North America, from Canada to Mexico. Their bright yellow and black markings closely resemble the warning coloration of stinging insects like wasps and honeybees, however, unlike the insects they mimic, these flies are harmless to humans and do not sting. As adults, they feed on nectar and pollen, and are essential for pollinating a wide diversity of plants. Additionally, their larvae play a crucial role in pest management by preying on aphids and other garden and agricultural pests. Their fascinating mimicry, significant ecological role, and contribution to natural pest control mechanisms, highlight the complexity of ecological relationships and the need for conservation efforts to protect habitats supporting these beneficial insects!
In 2022, People & Pollinators Action Network (PPAN) championed CO Senate Bill 22-199 at the legislature, in which the CO Department of Natural Resources commissioned a study on our state's native pollinating insects.
Insects, often underestimated, play a remarkable role in our state's landscapes. Not only are they cool, but they are also vital contributors to essential ecosystem services. From pollination to waste decomposition, insects support Colorado's diverse landscapes, from the mountains to the rivers.
Join us as we delve into the world of this fascinating wildlife and learn about the Colorado Native Pollinating Insects Study (2024) report! Check out pages 51, 84, 89, 91, and 114 to discover more about syrphid flies!
