European Spruce Sawfly
A moderately sized sawfly with dark brown to black coloring and pectinate antennae in males. Larvae are green with white lateral stripes and feed on spruce needles.
Did You Know?
After its introduction to North America in the 1920s, it caused massive spruce defoliation until a naturally occurring nuclear polyhedrosis virus brought populations under control.
Japanese Dung Beetle
A tunneling dung beetle found in Japan and Korea that provisions underground brood chambers with dung balls. Males have a horn on the head used for fighting in tunnels. Important for nutrient cycling.
Did You Know?
Both parents cooperate in raising offspring, with the female shaping dung into brood balls while the male guards the tunnel entrance from intruders.
