🍓 Melanogaster Fruit Fly Care Guide

(Drosophila melanogaster — the small, non-flying variety)

Melanogaster fruit flies are the most common feeder for tiny mantis nymphs due to their small size, ease of culturing, and fast reproductive cycle.

🧪 Basic Setup

You’ll need:

• 32–48 oz deli cups or culture jars

• Ventilated lids (fabric mesh, coffee filter, or foam plug)

• Dry media

• Excelsior / coffee filters for climbing

• A starter culture of melanogaster flies

⸻

🥣 Fruit Fly Media

Use a commercial media or make your own. Good media includes:

• Potato flakes

• Brewer’s yeast

• Sugar/honey

• Vinegar or citric acid (mold inhibitor)

Add water until the media is like thick oatmeal.

⸻

🪵 Excelsior / Climbing Material

Add a handful of:

• Excelsior

• Coffee filters

• Bamboo shavings

This gives flies places to pupate and keeps the culture dry on top.

⸻

🌡️ Temperature & Humidity

• Temp: 72–80°F (higher = faster breeding)

• Humidity: Normal room humidity is fine

• Avoid condensation — too much moisture causes mold.
