Margined Calligrapher
Toxomerus marginatus

What it is
Toxomerus marginatus, is a common species of hoverfly. It is found in many parts of North America.
Where and when to find it
- Habitat
- You can find Margined Calligraphers in gardens, meadows, fields, and woodlands across most of North America, including nearly all of the United States.
- How to find it
- Look for them hovering near flowers, especially composites like daisies or asters. Watch them 'hover' in mid-air like a tiny helicopter. Try to spot their short antennae and large eyes to tell them apart from bees.
- Best time of day
- Spring through fall, active during sunny daytime hours.
How it lives
- What it eats
- Nectar and pollen from flowers as an adult; larvae eat aphids.
- What eats it
- Birds, spiders, predatory insects (if they aren't fooled).
Worth knowing
- This fly is a 'mimic'; it looks like a stinging bee to protect itself.
- You can tell it's a fly, not a bee, because it has only two wings (bees have four).
- Its larvae are tiny, slug-like creatures that eat garden pests.
- They are also known as hoverflies or flower flies.
- They perform an amazing 'hovering' flight, staying perfectly still in the air.
- They help pollinate many of our favorite fruits and vegetables.
Why it matters
Margined Calligraphers are important pollinators, helping many plants. Their larvae also eat aphids, helping gardeners.
