# Maize Calligrapher

*Toxomerus politus*

While most hoverfly larvae are voracious predators of aphids, the Maize Calligrapher is one of the few species whose larvae are herbivorous, feeding on corn pollen.

- **Taxonomy:** Animalia › Arthropoda › Insecta › Diptera › Syrphidae › Toxomerus
- **IUCN Red List status:** Least Concern
- **Population trend:** stable
- **Biome:** grassland
- **Habitat:** Agricultural fields, maize crops, grassy meadows, and backyard gardens.
- **Diet:** Adults feed on nectar and pollen; larvae are unusual among syrphids for feeding directly on plant pollen, particularly maize.
- **Range:** North America, Central America, Caribbean
- **Size:** 6 to 8 mm in length
- **Lifespan:** 1 to 2 months
- **Active:** diurnal
- **Threats:** Widespread pesticide application, loss of wild field margins, and intensive monoculture farming.
- **Safe to approach?:** Harmless. Despite their wasp-like yellow and black stripes, Maize Calligraphers are completely stingless and bite-free hoverflies. You can safely observe them from inches away as they hover motionless in mid-air. If one lands on you, it is likely just drinking your sweat for minerals; simply enjoy the encounter or gently blow on it to encourage it to fly away.
