Kaston provides no less than 8 dorsal views of T. frondeum, each showing a different pattern on the abdomen.

Its background color is white but often with a tinge of yellow or green. Along the carapace and abdomen are medium black markings that exhibit considerable variation. Some individuals may lack the black markings while others may have very broad dark bands on either or both the cephalothorax and abdomen. The legs are long, especially leg I. In this leg, the patella plus tibia is nearly twice as long as carapace. The legs are dull greenish to white color with distinctive black bands which delineate the distal ends of each segment in leg I, and in all but the femurs of legs II and IV, but not at all in leg III.(1)

Life Cycle
The mother lays her eggs in a secluded spot, often under a folded leaf. She stays with and guards the babies for a few days after they hatch, and then the babies disperse.
