They are pretty ugly - who would believe they would turn into cute litte red and black spotted things. To all those who want to see what they look like just type baby ladybirds into google images and you should get one or too
But they are worth it to eat the aphids.
In fact you could probably transport them from your garden shop to your garden as you can even buy them in baby stage (or full size - but risk of flying away) over the internet So they probably would not mind the move
