Beetles
Rufus Isaacs, MSU Entomology
Several species of ladybeetles are active in blueberry fields. They are generally oval and red to orange with varying numbers of dark spots. Both adults and larvae are predators, eating aphids and other small insects.


Ladybeetle eggs are yellow and barrel-shaped and laid in clusters.

 
Larvae have dark, elongated bodies with orange markings and well-developed legs.

The multicolored Asian ladybeetle, an introduced species, feeds on pests during summer. They may be many colors with several or no spots.
The Asian ladybeetle can be distinguished from other ladybugs by the black M or W (depending on the viewing direction) between the head and abdomen (see photo).
Ground beetles eat insects and weed seeds. They can feed on insect eggs, larvae, and pupae that are found on the ground, and some may search in the bush canopy for food.
