  Beetles (order Coleoptera, infraclass Neoptera, subclass Pterygota, class Insecta, subphylum Hexapoda, phylum Arthropoda, kingdom Animalia)

  

Beetles are the largest insect order; over 350,000 species of beetles have been documented.  This means that over a quarter of all known animal species are beetle species. 

Beetles have "sheathed" wings: their forewings have become protective shells, called "elytra," for their membranous hind wings, which actually do the flying.  This is only one of fourteen identifying characteristics of beetles, but one of the two earliest characteristics to appear: beetles have had elytra for the past 285 million years.  Their hind wings, made of membrane and which are folded up under the elytra, are a later development (245 million years ago), at least for the 90% of beetle species in the suborder Polyphaga (Grimaldi & Engel, 2005, p. 361).  Their hind wings are much bigger than their elytra forewings, sometimes sticking out from under these covers when flying beetles land.  Do they have trouble folding up their big hind wings?  Some Soldier Beetles do, apparently! 

Beetles undergo complete metamorphosis, i.e., they experience a pupa stage during which their anatomical structure changes dramatically.

Unless stated otherwise, all taxonomic categories on this page were checked for validity against the contents of the Integrated Taxonomic Information System.

Ladybug Beetles (family Coccinellidae, superfamily Cucujoidea, infraorder Cucujiformia, suborder Polyphaga)

Almost all Ladybug Beetle species are carnivorous: all those that appear on this page are.  However, it appears that they (as do many carnivorous species) also include flower nectar in their diets.  Both Ladybug Beetle larvae and adults walk rapidly over the irregular surfaces where they are most often found; they are often seen charging up one side of a grass blade and down the other.  They often, though not always, find their way to any aphids in the general area, and process them relatively slowly.

This shows different species of ladybugs that appeared in my part of the country (north-central North Carolina).   Notable in its absence is the Convergent Ladybug Beetle (Hippodamia convergens).  The Multi-colored Asian Ladybug Beetle, on the other hand, is very common and, as its English name suggests, shows a great deal of intra-species variation, not simply in color but in size of spots.

Multi-colored Asian Ladybug Beetles (Harmonia axyridis)

Durham, 5/3/05.  This might be a Multi-colored Asian Ladybug (19-spot) Beetle (Harmonia axyridis).  Unlike native ladybugs, they try to enter houses and become pests in the process. Multi-colored Asian Ladybug Beetle, Durham, 9/9/05.  Yet another Multi-colored Asian Ladybug Beetle,  Moses Cone Memorial Park, Watauga County, NC, 8/8/06 Yet another Multi-colored Asian Ladybug Beetle, Durham, 7/5/05

 

This is also a Multi-colored Asian Ladybug Beetle, according to BugGuide's Harmonia axyridis guide page. NC Botanical Garden, 6/19/05 Multi-colored Asian Ladybug Beetle, Durham, 7/13/06.  Slightly smaller spots than those of the beetle on the immediate left. Durham, 11/4/05.  This Multi-colored Asian ladybug quickly freed itself from this spider web by somehow causing the strand it was on to lengthen and weaken. This Multi-colored Asian Beetle was trying to take off without success; it was obviously injured.  The spots are on the way to appearing.  Moses Cone Memorial Park, Watauga County, NC, 8/8/06 Multi-colored Asian Ladybug Beetle, Southern Village, Orange County, NC, 11/13/07.  The spots have just started to come out on this recent metamorph.

Multi-colored Asian Ladybug Beetle (Harmonia axyridis) larvae

 
Multi-colored Asian Ladybug Beetle (Harmonia axyridis) larva, Durham, 6/14/05.  This larva showed up on my deck.  Pretty big legs! Same Multi-colored Asian Ladybug Beetle larva Multi-colored Asian Ladybug Beetle larva, Eno River SP, Old Cole Mill Road access, Orange County, NC, 6/15/06.  Alas, this is also the season for late instar Wheel Bug nymphs, which make short work of these larvae. Multi-colored Asian Ladybug Beetle larva, Eno River State Park, Old Cole Mill Rd. access, Orange County, NC, 6/15/06  

Seven-spotted Ladybug Beetle (Coccinella septempunctata)

Seven-spotted Ladybug Beetle (Coccinella septempunctata), Durham, 5/7/08 Seven-spotted Ladybug Beetle (Coccinella septempunctata), Durham, 4/27/07. Seven-spotted Ladybug Beetle (Coccinella septempunctata), Durham, 9/12/05.  ID according to Charles Schurch Lewallen at Bugguide.net.  See larva below, IDed referring to same page.


       
Seven-spotted Ladybug Beetle (Coccinella septempunctata) larva, Durham (edge of marsh at neighborhood swamp), 4/11/09.  This plump but nimble little rascal climbed rapidly over grass plants and other objects, readily bending in two. Seven -spotted Ladybug Beetle larva, Duke Gardens, 3/28/07.  This larva, much skinnier than the one on the left, appeared on the steps at the central terrace. Seven-spotted Ladybug Beetle pupa, Durham, NC, 5/1/08 Ladybug beetle pupa, Mason Farm Biological Reserve (area north of the creek), 4/28/07.  Since there were 10+ Seven-spotted Ladybug Beetle adults in the immediate area, it seemed likely that this was one, too.        

Spotted Ladybug Beetle (Coleomegilla maculata)

         
Spotted Ladybug Beetle (Coleomegilla maculata) mating pair, Durham (neighborhood marsh), 6/18/05.  This is the most abundant species by far in this marsh. Spotted Ladybug Beetle (Coleomegilla maculata) mating pair, Durham, NC, 6/17/06, in my neighborhood marsh/swamp. Spotted Ladybug Beetle (Coleomegilla maculata) larva, Durham, 6/23/05, seen on a cattail leaf at the same marsh as the adult Coleomegilla maculata beetles above.  ID based on Marshall (2006), p. 345.          

Cycloneda genus

 
Ladybug Beetle (Cycloneda munda), Duke Forest, Korstian Division, Orange County, NC, 5/3/06.   Thanks to Eric Eaton for genus ID.  

Psyllabora vigintamaculata

Possibly Psyllabora vigintamaculata, Little Scaly Mountain, Macon County, NC, 8/9/05.  ID based on Marshall (2006), p. 349.  This beetle showed up at an altitude of about 4100 feet in far southwestern North Carolina.

Ladybug Beetle Pupae

The sequence in the first row (ordered photos of different pupae, taken on one or two leaves of the same tree) illustrates the changes Ladybug Beetle pupae of one species go through.  On the left is a new pupa, with the long, thin shape of a larva and some larva parts still showing.  Later on, as the pupa matures, it takes on the round adult shape and the old larval body parts outside the pupa's shell disappear.

All of the pupae in the first row showed close to a swamp in my neighborhood.  Although their species is unknown, they are almost certainly not Multi-colored Asian Ladybug Beetles.  To judge from the species of the Ladybug Beetles seen in this vicinity, I would say they are most likely Coleomegilla maculata pupae.

Two views of a larva becoming a pupa, Durham, NC, 7/5/05. Pupa, Durham, 8/6/05 Pupa, Durham, 7/15/05.  See the leg sticking out the right side. Pupa, Durham, 6/18/05.  I found this sitting on a leaf.  This was about a third of an inch long.

This pupa was a member of another Ladybug Beetle species, the Multi-colored Asian Ladybug Beetle (Harmonia axyridis):

Durham, NC, 6/29/06

This pupa was found among a few similar pupae and many Seven-spotted Ladybug Beetle adults.

Snout Beetles (family Curculionidae, superfamily Curculionoidea, infraorder Cucujiformia, suborder Polyphaga)

There are about 50,000 species of curculionid snout beetles, also called weevils.  They are surprisingly easy to find, especially in brushy power line cuts.  If most species weren't so tiny, we'd probably be swimming in them -- at least if it weren't for Ambush Bugs, which lie in wait on flowering plants in brushy areas!  Nevertheless, there are some notable exceptions to the size rule: some weevils are almost an inch long.

Asian Oak Weevils (Cyrtepistomus castaneus), Johnston Mill Nature Preserve, Orange County, NC, 8/31/07

Weevil, Durham, 6/16/05.  Found on a swamp plant.  About ⅛ inch long, as were all the weevils in this row and the one just below it. Weevil, Durham, 6/20/05.  This and all the weevils to the right of this one in this row showed up in a power line cut in my neighborhood. Weevil, Durham, 6/20/05

 

Mating weevils (Odontocorynus scutellumalbum, subfamily Baridinae), Durham, 6/20/05.  These black weevils showed up in a power line cut. Weevil, Durham, 7/15/05, front view.  Same weevil, as on left.  Durham, 7/15/05. Perhaps a similar weevil, but in a different light.  Durham, 6/2/06 Mating weevils, Penny's Bend, Durham County, NC, 6/4/06

 

Billbug (probably genus Sphenophorus), North Charleston, Charleston County, SC, 3/28/06.  About ¾ inch long.  ID thanks to Eric Eaton. A very big weevil, Lixus genus, Lixinae subfamily, Durham, NC, 5/25/06. It was about an inch long.   It showed up near a mini-swamp next to a power line cut.  Thanks to Eric Eaton for ID.

Primitive or Straight-snouted Weevils (family Brentidae, superfamily Curculionoidea, infraorder Cucujiformia, suborder Polyphaga)

Tiny weevil (about 2 mm long), North Carolina Museum of Art outdoor trail, Wake County, NC, 5/8/07. Oak Timberworm(Arrhenodes minutus), a type of straight-snouted weevil .   It was about 18 mm long.  ID thanks to John and Jane Balaban.  See more information at the Forest Pests Oak Timberworm Page.

Fungus Weevils (family Anthribidae, superfamily Curculionoidea, infraorder Cucujiformia, suborder Polyphaga)

Euparius marmoreus, Falls Lake SP, Wake County, NC, 3/1/06.  This beetle appeared near the end of a pier. Touching the beetle caused it to play dead briefly, after which it righted itself after some leg-wiggling. This shows the characteristic back pattern of the Euparius marmoreus.

Leaf Beetles (family Chrysomelidae, superfamily Chrysomeloidea, infraorder Cucujiformia, suborder Polyphaga)

Some Leaf Beetles, such as the Colorado Potato Beetles, were major crop pests because they were imported from outside North America while their natural predators were left behind.  Leaf Beetles in general are far less common than they used to be as a result of insecticide use.  However, they are still found munching on a variety of weeds and marsh vegetation in my neighborhood and at least a few other places.

Tribe assignments for Tortoise Beetles are taken from the Alabama Agricultural Experiment Station, Auburn University web page.   Most of the subfamily IDs are based on University of Minnesota's Insects of Cedar Creek.

Tortoise Beetles (Subfamily Cassidinae)

There is some controversy about whether this subfamily should stand alone or be a part of the Leaf-mining Beetle subfamily Hispinae.

 

Golden Tortoise Beetle (Charidotella bicolor), Durham, NC, 7/1/07.  These are photos of the same beetle, taken in different lighting. Golden Tortoise Beetle,  Durham, NC  9/10/06

Clavate Tortoise Beetle(Plagiometriona clavata, tribe Cassidini, sub-family Cassidinae)   Duke Gardens, 7/24/05.  Underneath its purely reflective  "shell" is something that looks like an ordinary beetle. It was about ¼ inch long.  It appeared in the main (terraced) garden.  Thanks to Jeff Pippen for the ID. Argus Tortoise Beetle (Chelymorpha cassidea, tribe Stolaini, subfamily Cassidinae ), north shore of Ocracoke Island, 5/15/05.  This beetle was about half an inch long.  Not sure of this ID.

Leaf-mining Leaf Beetles (Subfamily Hispinae)

Locust Leafminer (Odontota dorsalis, subfamily Hispinae), Boone, Watauga County, NC, 8/29/05.   The taxon "Hispinae" is valid according to the ITIS, which lists no genera under it as of 4/3/06.

Dogbane Beetle (Chrysochus auratus, subfamily Eumolpinae), Durham, 7/12/05.  It was about ½ inch long.  These beetles only eat milkweed and dogbane, so they are not pests.  Thanks to Betty Anderson for the ID.  Another Dogbane Beetle, Durham, 7/15/05. Mating Dogbane Beetles, Mason Farm Biological Reserve, Orange County, NC, 7/9/06 Dogbane Beetle, Daniel Boone Gardens, Boone, Watauga County, NC, 8/9/06 Dogbane Beetle, Penny's Bend Nature Preserve, Durham County, NC, 6/1507 Maybe a Grape Rootworm (Fidia viticida), Durham, 6/23/05.  We have a lot of wild grape vines in my neighborhood.

Chrysomelid beetle, possibly a Flea Beetle (Disonycha genus, Alticini tribe), Durham, NC, 4/19/06.  This beetle was visiting a dandelion.  Flea beetle, Durham, NC, 7/6/07.  A very tiny beetle. Flea Beetle (Disonycha fumata, Alticini tribe), Durham, 7/5/05.  This one was about ¼ inch long.

Spotted Cucumber Beetles (Diabrotica undecimpunctata, Luperini tribe)

This illustrates some interesting similarities.  A Spotted Cucumber Beetle (Diabrotica undecimpunctata, subfamily Galerucinae), at right, shared flower nectar with a (mainly carnivorous) ladybug beetle (Coleomegilla maculata) on 7/2/05.  Spotted Cucumber Beetle, Durham, NC, 7/29/07 Spotted Cucumber Beetle, Duke Forest, Gate 12, Durham, NC,  9/29/05.

Broad-bodied Leaf Beetles (Subfamily Chrysomelinae)

Burdock Beetle (Leptinotarsa juncta, subfamily Chrysomelinae).  I found this beetle munching on a leaf of one of my least favorite weeds (Horse Nettle).  Durham, 9/27/05.  Thanks to Eric Eaton for ID. Burdock Beetle. Same beetle, playing dead.  Close to looking like a Colorado Potato Beetle, but no cigar: the broad black stripe and the thorax markings set it apart. Probably Leptinotarsa genus, Chrysomelinae family member.  Durham, 10/31/05. Swamp Milkweed Leaf Beetle (Labidomera clivicollis), Eno River State Park, Orange County, NC, 10/9/06

Case-bearers, i.e., Cylindrical Leaf Beetles, Warty Leaf Beetles and Short-horned Leaf Beetles (Subfamily Cryptocephalinae)

They are called "cryptocephalid" because of the "hidden" orientation of their heads, i.e., at right angles to their bodies.  Females cover their eggs with their feces, which become a "case" that the growing larva builds on. 

Warty Leaf Beetle (genus Neochlamisus). A picture from the rear of this fast-moving beetle.  Durham, 7/31/05. Although most insects (and some treefrogs) seem to mimic dead leaves, this beetle is typically confused with caterpillar droppings, but only when it tucks its legs under it and lies motionless! Cylindrical Leaf beetle (Babia quadriguttata, tribe Clytrini), Durham, 6/2/06. Clay-colored Leaf Beetle(Anomoea laticlavia, tribe Clytrini), Penny's Bend Nature Preserve, Durham County, NC, 6/15/07.   Family ID thanks to Jim McClarin.

Passalid Beetles (family Passalidae, superfamily Scarabaeoidea, infraorder Scarabeiformia, suborder Polyphaga)

Adult beetles live under rotting logs and chew up the wood so their offspring can eat it.

Bess Beetle (Papilius disjunctus?), Eno River State Park, Fews Ford access, 12/31/05.  This beetle was grinding up rotten log material with its mandibles.  The Papilius taxon is valid according to the ITIS.  Species name given by Encyclopedia Britannica. Horned Passalus Beetle (Odontotaenius disjunctus), Durham, NC, 7/20/07.  Taken at night.

Scarab Beetles (family Scarabaeidae, superfamily Scarabaeoidea, infraorder Scarabeiformia, suborder Polyphaga)

These beetles perform an essential clean-up function: the adults move the feces of other animals underground, where they store it as food for themselves and their offspring.

Currently for this family, the ITIS does not list any taxons below subfamily for any species assigned to a subfamily.  However, the relevant genus and species names are in common use.

Tumblebugs (subfamily Scarabaeinae)

Tumblebug (Canthon imitator), pushing a clump of dung along with its hind legs at Eno River SP, Old Cole Mill Road access, 5/29/05.

Rose Chafer Beetle (Macrodactylus subspinosus), Indian Creek Trail, a Jordan Lake Game Land, Chatham County, NC, 7/7/06 An unidentified member of the Shining Leaf Chafer subfamily, Johnston Mill Nature Preserve, Orange County, NC, 6/16/07 Japanese Beetle (Popillia japonica), Durham, NC, 7/1/07

May/June Beetles (subfamily Melolonthinae)

These common names are used rather loosely, probably depending on what time of year these beetles show up in a particular part of the country. 

May Beetle (Phyllophaga rugosa), Durham, NC, 5/2/07.

Flower Scarabs (subfamily Trichiinae)

This subfamily seems to be controversial.
