Tips for Success
💡
Pro TipUse flightless/wingless varieties (apterous or vestigial wing) for much easier handling.
💡
Pro TipMelanogaster are smaller (2mm) and hydei are larger (3mm) — match to your animal’s size.
💡
Pro TipA warm spot (24°C) speeds up the cycle; a cool spot (18°C) slows it — useful for timing production.
Common Problems & Warnings
⚠️
WarningMites are the #1 threat to fruit fly cultures. If you see tiny moving dots on the lid, discard the culture immediately.
⚠️
WarningNever use fully sealed containers — the culture needs air exchange or it will grow mould.
⚠️
WarningFruit fly media can attract wild fruit flies — keep cultures in a sealed room or cabinet.
