False Bombardier (Galerita bicolor)

The false bombardier beetle is a part of the ground beetles family indigenous to the United States. This species has attained its name as it mimics the shape and colors of the bombardier beetle to shield itself from predators.

False Bombardier Beetle

Scientific Classification

  • Family: Carabidae
  • Genus: Galerita
  • Scientific name: Galerita bicolor

Physical Description and Identification

Adult

Size: 17 – 25 mm (0.66 – 0.98 inches)

Color: It closely replicates the bombardier beetle’s colors, having a black abdomen and head and an orange thorax and legs.

Galerita bicolor

Larva

Not much detail about the larvae is recorded, only for the fact that they appear long and cylindrical like the bombardier beetle’s larva.

Pupa

The pupation phase takes place near leaves and woody regions where the larva inhabits.

Egg

The females make mud cells that are purse-shaped within the undercol3s of leaves and lay eggs there.

Quick Facts

Adult lifespan1 – 2 years
Duration of larval stageNot recorded
DistributionEastern parts of United States
HabitatWoodland, moist areas, leaf litter, logs, rocks, backyards
Common PredatorsBirds
Seasons active fromFebruary – November
Host PlantsNo host plants
Diet of larvae and adultsInsects
False Bombardier

Identifying the Damage Caused by Them

They mostly feed on insects roaming around their habitats, so they are not likely to cause damage to the plants in the areas they live.

Did You Know

  • These beetles are two times larger than the bombardier beetle that they mimic.
  • Their species name was first described in 1773 by British collector Dru Drury.
