Names preceded by an asterisk indicate common names that I have made up.

American Cockroach

Accidentally introduced before 1882, probably from North America.

German Cockroach

Unknown Cockroach

Accidentally introduced before 1882, probably from North America.

Burrowing Cockroach

	Ventral view.

	Dorsal view. Cockroach is 2 cm long.

Brown Banded Cockroach

Pacific Beetle Roach Mimic

Unidentified Tenebrionidae Beetle

	This beetle is 1.2 cm long.

Blister Beetle

	Dorsal view.

	Side view. Body length is 10mm.

False Blister Beetle

	Body length 10 mm.

Eucalyptus Long-horned Beetle

This is a non-native species, established in Hawaii since 1965.

Small Beetle

This beetle is about 3 mm long. Identification made by Bishop Museum. Introduced species.

Powder-post Beetle

	Dorsal closed.

	Ventral closed. Beetle is 3 mm long.

	Ventral beginning to open.

	Ventral ½ open.

	Ventral fully opened. The larva of these beetles eat wood. Specimens are about 2.5 mm long.

Elaterid Click Beetle



	Beetle on the left (dorsal view) shows wing on the right half. Beetle is approximately 10 mm long.

Bark Beetle

	Dorsal view. Wing extending from under carapace.

	Ventral view. Wing extending from under carapace.

	Two specimens, both with wings showing. The body of this small beetle is only about 2 mm in length.

Bark Beetle type 2

	Dorsal view.

	Ventral view. Body length = 2mm.

Gonocephalum Darkling Beetle

	Dorsal view. Note bilateral blackish spots.

	Ventral view. Beetle is 4 mm long.

7 mm Beetle

	Side view.

	Dorsal view.

Rove Beetle

	Dorsal view.

	Side view.

	Head close-up. Beetle length = 1.3 cm. Per Frank Howarth of the Bishop Museum this “is a rove beetle, family Staphylinidae. From the color pattern, size, and what I can see of its form, it is probably Thyreocephalus albertisi (Fauvel, 1877) which was purposefully introduced as a generalist predator of agricultural pests. Rove beetles are mostly predators but also scavenge on rotting animal remains.”

Tenebrionid Beetle

	Dorsal.

	Side.

	Ventral. This beetle is 9 mm long. Found in rotting log. Per David Preston of the Bishop Museum “This appears to be the Tenebrionid beetle Uloma bonzica Marseul 1876. They are associated with decaying plant material and the species was first collected by Al Getmann in the mid-eighties from rotting banana stumps.”

Chinese Rose Beetle

	Dorsal view.

	Side view.

	Ventral view.

	Close-up of ventral side of head. This beetle is 1 cm long. This species was accidentally introduced sometime before 1896. It is native to Japan and Taiwan.

Lyctid Beetle

Rhipidius Beetle

This beetle is about 2.8 mm long.

Giant Click Beetle

	Dorsal view.

	Ventral view. Per Frank Howarth of the Bishop Museum “This is a giant click beetle, accidentally introduced from Central America. The name is Chalcolepidius erythroloma Candeze, 1857, family Elateridae. The larvae are predators and scavengers in rotting wood, and the adults feed on fruits and considered minor pests. The adults make good pets as they are long-lived and have such a spectacular jumping ability.”

Burrowing Beetle

	Side view.

	Ventral view.

	Dorsal view. This beetle is 5 mm long.

Black Beetle

This beetle is 6 mm long. ID by David Preston of the Bishop Museum.

Phenolia Beetle





	This beetle is 7 mm long. ID by David Preston of the Bishop Museum.

Ceresium Long-horned Beetle

Body length is 13 mm.

Curtomerus Long-horned Beetle

This introduced species is common in Hawaii and attacks a wide range of woody tree and shrub species. Body length is 8 mm. Species identification by Frank Howarth of the Bishop Museum.

Body length of this beetle is 6 mm. ID by David Preston of the Bishop Museum.

Burrowing Bug



	This beetle is about 6 mm long.

Cigarette Beetle

	Dorsal view.

	Ventral view. Body length about 2mm. Per Frank Howarth of the Bishop Museum: “This tiny beetle is in the family Anobiidae, which includes many stored product pests and powder-post beetles. Hawaii has many (about 100 species) native wood borers in this group, but your specimen appears to be either the cigarette beetle (Lasioderma serricorne) or the herbaium beetle (Tricorynus herbarium), both of which feed on a variety of dried household products (yes even tobacco!).”

Mango Flower Beetle
