Golden Delicious Melanogaster Fruit Fly Culture for Sale Golden Delicious is a small, golden, flightless fruit fly, a strain of Drosophila melanogaster. TC offers it as their smallest feeder fly, which makes it a good match for the tiniest animals. The golden color also helps, since the pale flies are easy to see against dark substrate. It arrives as a live, producing culture in a 32oz cup with Super Swarm Media, and it is just as prolific as the other melanogaster. What Makes Golden Delicious Different? Two things set this strain apart from the other melanogaster. First, the small size targets the very smallest animals that struggle with larger feeders. Second, the golden body is easy to spot, so you can judge feeding at a glance. Aside from those traits, care matches our standard wingless melanogaster and Golden Wingless melanogaster. Honest Note on Size and Color TC lists Golden Delicious as the smallest of their fruit flies, but the size still sits around 3mm, close to the standard melanogaster. So treat it as among the smallest feeder flies rather than guaranteed smaller, and pick it when you want a small, visible fly for tiny animals. The golden color helps visibility, but it does not change nutrition. Therefore, still dust the flies with calcium and a multivitamin before feeding, using a product such as TC Calcium Ultra Fine. Using Your Culture Care matches the other melanogaster, so the steps below are the short version. Starting a Fresh Culture Give a fresh culture about 10 to 12 days to lay eggs and build up. However, if the cup already holds larvae or pupae, you can feed right away. Conditions Keep the culture at normal room temperature and out of direct sun. Stable warmth keeps production steady. 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 Newly morphed and thumbnail dart frogs that need the smallest prey. The smallest mantis nymphs and tiny spiderlings. Small fish and other animals that take very small feeders. Keepers who want a small fly they can see clearly while feeding. Not Best For Larger animals, since these flies are very small and better for tiny pets. Keepers wanting a bigger fly, who may prefer Hydei. Keepers who will not dust feeders, because small size does not change the low calcium content. Recommended Add-Ons TC Calcium Ultra Fine to dust flies before feeding. Springtails as another tiny feeder for froglets and small animals. Hydei Fruit Fly Culture to step up in size as your animals grow. Super Swarm Fruit Fly Kit to culture your own flies at home. Fabric Vented Lid for culturing flies in your own 32oz cups.
