Golden Hydei Fruit Fly Culture for Sale
Golden Hydei is a golden, yellow-bodied form of the larger fruit fly Drosophila hydei. At around 4mm, it offers the bigger hydei size in a color that is easy to see against dark substrate. Many keepers also report that it produces faster and longer than standard hydei. It arrives as a live, producing culture in a 32oz cup with Super Swarm Media, and it suits bigger animals rather than the tiniest ones.
Why Golden Hydei?
This strain brings together three useful traits. First, the golden body stands out, so you can judge feeding and spot flies easily. Second, the larger hydei size fits bigger frogs and juveniles. Third, many keepers find it a strong, steady producer.
Aside from color, care matches our standard Hydei. For a smaller golden fly, see the Golden Wingless Melanogaster.
Honest Note on Color, Flight, and Production
Golden is a color form, so it does not change nutrition. For that reason, still dust the flies with calcium and a multivitamin before feeding. The reports that this strain out-produces standard hydei come from keepers, so treat heavier or longer production as a likely bonus rather than a guarantee.
Like all hydei, these flies are flightless but can regain some flight if a culture gets too warm. Therefore, keep cultures cool and stable, and keep a lid handy when harvesting.
Using Your Culture
Care follows the same routine as standard hydei, so the steps below are the short version.
Starting a Fresh Culture
Give a fresh culture about two weeks to build up, since hydei is slower than melanogaster. However, if the cup already holds larvae or pupae, you can feed right away.
Conditions
Keep the culture at a stable, moderate room temperature and out of direct sun. Avoiding heat also helps keep the flightless flies grounded.
Harvesting and Dusting
Tap flies into a separate cup, then dust them with calcium and a multivitamin before feeding. Tapping the cup down keeps the flies from climbing out.
Best For
- Larger dart frogs and bigger juvenile reptiles and amphibians.
- Keepers who want a larger fly they can see clearly while feeding.
- Small chameleons, geckos, and mantises that take a bigger fly.
- Keepers who want a steady, productive larger culture.
Not Best For
- The tiniest animals, such as froglets, which do better on smaller melanogaster.
- Keepers who need flies fast, since hydei cultures start slower.
- Keepers who will not dust feeders, because color does not change the low calcium content.
Recommended Add-Ons
- TC Calcium Ultra Fine to dust flies before feeding.
- Standard Hydei for the same larger fly in its normal color.
- Golden Wingless Melanogaster for a smaller golden fly for tinier animals.
- Super Swarm Dry Fruit Fly Media to culture your own flies at home.
- Fruit Fly Combo: 5 Species to try several strains together.
Frequently Asked Questions
What is Golden Hydei?
It is a golden, yellow-bodied color form of the larger fruit fly Drosophila hydei. At around 4mm, it suits bigger small animals.
How is it different from standard Hydei?
Mainly the golden color, which is easier to see. Many keepers also report it produces faster and longer than standard Hydei. Otherwise, the two are the same larger fly.
How is it different from Golden melanogaster?
Golden Hydei is larger, while Golden melanogaster is smaller. Choose by the size of your animal.
Is the golden color more nutritious?
No. Color does not change nutrition, so still dust the flies with calcium and a multivitamin before feeding.
Do Golden Hydei flies fly?
They are flightless, but they can regain some flight if a culture gets too warm. So keep cultures cool and keep a lid handy.
When can I start feeding from it?
Give a fresh culture about two weeks, since hydei is slower than melanogaster. If it already contains larvae or pupae, you can feed right away.
