Golden Hydei

I ordered a couple of cultures and went seed new cultures to find that there were regular black hydei mixed in with the golden. I have not had hydei for several months so I can't believe there was external contamination. Is this strain producing both types of flies? Should I not use this batch to re establish my hydei cultures? Will these guys cross back into fliers? Anyone else get mixed cultures of these?

I hadn't even thought about the "golden" aspect of my Hydeii's in ages.

I just took a look and they really don't seem all that Golden anymore!

But there does not appear to be mulitple color types either - just darker than they were before (though not black).

Agreed,Mine also have diminished in their golden glory.

The gold color is simply an induced mutation. It can sway back and forth based on gene sprting, but the mutation can get bred out so to speak.

If the gold were a simple single mutation, one would expect either gold flies or black flies, not faded flies though. They all seem to fade uniformly, as well.

Well so much for these GUCCI designer flies :!: I guess the "new and improved" white ones and the "new and improved" smaller ones will probably breed out as well.

I don't know about the white ones, but the smaller ones are actually a different species, which happens to be smaller (that is if you are talking about the Drosophilia simulans).

Just feed out of the end of your cultures for "smaller" food.

How exactly do you modify a fruit fly?

forget the blue eye, gold eye, upside down fly, and think of what the frog would eat. Basically anything it can get in its mouth and is moving. I sometimes wonder why some of these advertisers of morphed flies spend so much time in trying to convince the frog community that their white eyed or gold eyed or whatever is going to make the difference in the frogs appetite. The question should be..........does the frog really care?

So here is the answer from our perspective. Offer as much of a variety of
food prey as possible, watch what will be eaten and get to know your frogs eating habits instead of your flys mating habits!
