Halgerda willeyi is characterized by several yellow ridges with a series of yellow and black lines between them. The body colour is translucent whitish.
Species in the genus Halgerda are usually differentiated by their colour patterns. At present it is difficult to determine whether Halgerda willeyi has a very variable colour pattern or whether there is a number of very similarly coloured species. This shot shows the typical colour variant of Halgerda willeyi .
A possible dark colour variant without yellow piment on the ridges is Halgerda sp. 01.
