How long does it take for mealworms to pupate?
Raising Mealworms: Everything You Always Wanted to Know (and more)
| Stage | Time* |
|---|---|
| Egg Incubation | 4-19 days (usually 4-7). Another source says 20-40 days |
| Larva | 10 weeks. Visible after about a week |
| Pupa | 6-18 (18-24?) days |
| Beetle and Egg Laying | 8-12 weeks (followed by death). Egg laying starts 4-19 days (average 12) after emergence |
How do mealworms turn into pupa?
During the larval stage, the mealworm feeds on vegetation and dead insects and molts between each larval stage, or instar (9 to 20 instars). After the final molt it becomes a pupa. The new pupa is whitish, and it turns brown over time.
