G.baldianum flower abort

[Greenlarry]

The G.baldianum that I bought in summer had a big flower bud developing while in the greenhouse, but as it was getting cold I brought indoors. The bud began to open then suddenly it began to wither. Probably too late in the season. When I bought it it had a ring of flower buds but when the large one developed the others atrophied.

Some cacti just don't like being moved.....

Update, I just noticed webbing at the base of the bud, and inside was a tiny green caterpillar!

The caterpillar wouldn't help! Gymnocalycium flowers generally like quite a bit of warmth to open. If they don't get it for a few weeks then the flower will just give up, or maybe it did even open a few times without you spotting it.

I always find that my Gymnocalycium flowers open in the afternoon. If the day is dull and cloudy then flowers that are trying to open won't open fully, or at all.
