OPEN THE GATES
On arrival
Keep the culture upright and inspect the lid, medium, and adults. Check whether it was sold as freshly started or already producing. A fresh culture may contain developing stages before it produces a large number of visible adults.
BUILD THE REFUGE
A secure holding setup
Use a secure cup with fine breathable ventilation, prepared medium, and clean climbing material appropriate to the culture. Keep the lid in place except during controlled transfers. Flightless or wingless strains can still climb and escape through gaps.
KEEP A STEADY WATCH
Temperature & placement
Common Drosophila cultures are generally maintained around 68–77°F (20–25°C), away from direct sun. Avoid hot enclosure tops and prolonged overheating. Development varies with species and conditions; hydei and melanogaster should not be expected to produce on exactly the same schedule.
PROVISION THE COLONY
Food & hydration
Prepare the culture medium according to its label. It should support development without becoming flooded, dried solid, or excessively contaminated. Do not add water by guesswork to a failing culture. Use clean cups and tools when starting fresh batches.
Prepare with Fruit Fly Culture Media, Fabric Vented Lid (Fits 32oz Deli Cup). Check each product’s directions before use.
THE DAILY WATCH
Care between feedings
Start dated backup cultures before the current one stops producing. Transfer only part of the adults so the parent culture retains stock. Inspect for mites and spoilage, and separate suspect cultures from clean backups. Tap a controlled portion into a feeding cup, then close the lid promptly.
AVOID THE COMMON TRAPS
Mistakes worth preventing
- Treating every named color or strain as the same species.
- Overheating cultures to force faster production.
- Harvesting all adults from your only producing culture.
