Spawn beetle

Spawn beetles

Spawn beetles were a type of insect known for their fascinating striations; they came in at least three different colors: pink, blue, and green. Spawn beetles could be used to cross-pollinate Oblissian cabbage. Kes kept some spawn beetles in airponics.

When Kes underwent a premature surge of elogium in 2371, she ate several spawn beetles, as she couldn't control her appetite. (VOY: "Elogium")

The spawn beetles seen in this episode were trained by John Baldwin and Karen Thomas-Kolakowski of Critters of the Cinema.
According to Jennifer Lien, the actual prop bugs she was eating "were actually made of Jello." (Starlog #226, May 1996, p. 44)
