How can you tell the difference between a lacewing and fallow budgie?

Here are some of the common differences between these 2 mutations with pictures to help you identify each mutation. Look at the cheek patches, body color, and main tail feathers for the best indications of which mutation your budgie is.

Lacewings will have pale to light violet cheek patches. A fallow budgie on the other hand will usually have a much deeper violet color to the cheek patches.

Lacewings will have 100% diluted body color. Fallows will have a great deal of dilution on the upper chest and belly, with the intensity increasing toward the vent and rump.

On the left you can see examples of the complete dilution in lacewings, and on the right fallows with 90-50% diluted body color from the chest to the rump.

Complete dilution (with the exception of slight suffusion on some birds) on whole body, including vent and rump area

Heavy dilution on neck/chest with color increasing toward vent with the rump being the brightest

The main tail feathers of these 2 mutations are very different. Lacewings will have light to medium cinnamon, while a fallow will have a blue/grey main tail feathers.
