Spawn beetles were 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 2372, she ate several spawn beetles, as she couldn't control her appetite. (VOY: "Elogium")
