There are many ways a small animal can mislead predators or
prey by disguising itself. The most obvious ways are by 1) looking like a
more dangerous animal, 2) looking like something uninteresting or 3) becoming
invisible by blending into its surroundings. Sometimes, though, these
animals make mistakes, and we humans sometimes unintentionally set them up to do
so.

Virginia
Hover Fly
(Milesia
virginiensis, subfamily Eristalinae), Johnston Mill, Orange County, NC, 7/1/06.
Note the flattened abdomen, a characteristic apparently peculiar to syrphid flies.
This relatively large fly (sometimes almost an inch long) can look
menacing when it hovers in the air right in front of you. But it's
just bluffing. |

Harmless checkered beetle (Enoclerus ichneumoneus), Penny's Bend Nature
Preserve, Durham County, NC, 4/4/09. Granted, this insect is
never found in the same environments as the Cowkiller and hardly
moves. It may be a coincidence that they look so similar, but as
we'll see later, red and black are a winning combination. |
Spider wasp
(Psorthaspis mariae), Falls Lake Dam area, 9/11/10. It successfully mimicked a velvet ant while

The Predator Look
These animals generally look as if they have big heads. Eyespots
imply this, but sometimes the design represents complete mimicry of a long jaw
with many teeth. Sometimes, though, the animal just looks heavily armed.

Basilica Spider (Mecynogea lemniscata), dorsal view of the abdomen, Durham, NC, 7/20/05.
This view suggests the gaping jaws of a snake, with fangs and tongue. |
See the eyespots
on this late-instar Eastern Tiger Swallowtail (Papilio glaucus), caterpillar, Indian Creek Trail,
Jordan Lake, Chatham County, NC, 9/3/06. To judge from the threads on
either side, it might have been about to become a chrysalis, but in
other circumstances it may have reared its head and tried to look
aggressive. |
Crablike
Spined Orb Weaver (Gasteracantha cancriformis), Cypress Gardens, Berkeley County, SC,
10/12/07.
The spines certainly make it look unappetizing; whether
it looks like a scary face, though, is a matter of opinion. If you
unsuspectedly wreck its web and it winds up in your hand, it feels like
a sandspur.

Beech Blight Aphids (Grylloprociphilus

This species often tries to hide in the brush. |
Banded
Hairstreak (Satyrium calanus), Durham, NC, 6/10/08. Both
eyespots and skinny wiggling parts here. Hairstreaks typically rub
their hind wings together to create the illusion of an eyed creature

Oak Timberworm (Arrhenodes minutus), a type of straight-snouted weevil. It is brown in nonreflected
light. |
Brown Prionid (Orthosoma
brunneum, Prionini tribe), Durham, NC, 7/7/08. This beetle has a cool
strategy: in the daylight (or in dim noctural light), it's brown and
uses camouflage. But in reflected light (in this nighttime photo)
it looks red and apparently poisonous. |
Golden Tortoise Beetle (Charidotella bicolor),
Durham, NC, 7/1/07. |
Golden Tortoise Beetle (Charidotella bicolor),
Durham, NC, 7/1/07. This is the same beetle as that on the left, taken in a different light. Here it reflects its green environment. |

Just to add to
the confusion, one more Golden Tortoise Beetle, Duke Gardens,
Durham, NC,
7/24/05, reflecting nearby flowers. |
Soft-winged
flower beetle (Collops genus), which can't seem to make up its mind
about fight or flight. A combination of scary red and camouflage
green during the day, it becomes red and black in dim light. Seen in neighborhood marsh.

|
Warty Leaf Beetle (Neochlamisus
gibbosus, Chlamisini tribe, Cryptocephalinae subfamily), Durham, NC,
5/10/08. This beetle is typically confused with
caterpillar droppings, but only when it tucks its legs under it and lies
motionless! |
Wavy-lined Emerald
(Synchlora aerata)
caterpillar, Asheboro, NC, 8/18/07. These caterpillars camouflage
themselves by attaching plant debris to their bodies, giving them a
withered look. |
Leaf insect
(ventral view). Audubon Insectarium, New Orleans, LA, 10/25/08. It

been better hidden on the ground. |
Yellow-necked Caterpillar

Ambush Bug,
Mason Farm Biological Reserve, Orange County, NC, 9/17/08.
At a distance, this insect looks like a wilted flower on this type of
plant. When there only seems to be one on the entire plant, it's
almost always an Ambush Bug. |
This Ambush Bug has
turned green to suit the occasion. Durham, NC, 8/23/08 |

shore. |
Northern Cricket Frog
(Acris crepitans),
Penny's Bend Nature
Preserve, Durham County, NC, 10/21/06. This frog was very far from
water, on the side of a very tall hill in the woods, although it looks
as though it would be at home in an environment with moss or algae. It did get the
mottled look right, though. |

Green Anole (Anolis
carolinensis),
Ocracoke, Hyde County, NC, 5/15/05. When
green, anoles are well-disguised among grass and succulent plants. |
This Loíza (Puerto Rico)
anole demonstrated very effective camouflage on 10/12/06. |
Whitish tiger beetle (Cicindela gratiosa), Carolina
Beach State Park, New Hanover County, NC, 6/23/06. It was
springing around like a fly, and all I could see was motion at first. ID thanks to Patrick Coin of
Durham, NC. |
American Toad (Bufo
americanus), Eno River
SP, 5/2/03. Superb camouflage! This toad blends in well with the
forest floor, a combination of small, relatively unhealthy green plants and dead leaves. |

1/31/09. This bird looks like a hunk of tree
bark. |
Mallard family,
Durham, NC, 4/13/08 |

Barn Swallow
(Hirundo rustica)
about to fly under the Pasquotank River Bridge between Pasquotank and
Camden Counties, NC, 4/27/09. The blue blends in well with the
bodies of water they are always near when they fly, but their brown
"faces" are what show when they're in their nests, which are built on
sides of walls. |
Female Northern Flicker
(Colaptes auratus), showing a rear view of the head. Durham, NC,
3/19/09. Generally seen in my neighborhood in the early spring, this
bird blends in well with mostly bare
tree branches and Red Maple blossoms. |
Mourning Dove (Zenaida macroaura), Durham, NC,
11/1/06. This bird is relatively well-hidden in an environment of
gravel, soil and dead leaves. |
Anhinga (Anhinga anhinga), Audubon Swamp Garden, Charleston
County, SC, 3/28/06. Its black-and-white coloring helps this bird
hide in trees even in the winter. |

A Common Oak Moth
(Phoberia atomaris) managed to slip under a pine needle and part of a
leaf in a split-second landing at the North Carolina Botanical Garden, Orange County, NC,
3/17/11. These moths
were very common in this area that day, but extremely fast-moving and
often impossible to see when they landed. I got this photo by
aiming the camera where I saw the moth land, without actually seeing it! |

Camouflage mistakes:
Sometimes animals either fail to adjust their skin
to the right color or pick the wrong background.
|
|
|
Gray Treefrog
(Hyla
chrysoscelus) or Copes' Gray Treefrog
(Hyla versicolor), Durham, NC,
7/27/08. This frog's problem may be due to malnutrition or
illness, since "gray" treefrogs are normally not all gray. |
Northern Cricket Frog
(Acris crepitans),
White Pines Natural Area, Chatham County, NC,
9/25/05. It's really hard to imagine what this frog was thinking. |
Looks like a brown
American
Green Treefrog
(Hyla Cinerea).
Durham,
10/18/06. Seen in a power line cut near a creek.
Since it was late in the year, near the end of insect season, the frog
may have been malnourished. |
Animals that rely on camouflage have special difficulties
adapting to artificially produced environments, especially those with solid
colors or those simply not found in certain natural environments.
|
|
|
|

Green Anole (Anolis carolinensis),
Ft. Fisher State Recreational Area,
New Hanover County, NC, 10/12/06. You can see some pigment changes
on the head and tail, resulting in four different colors. |
Rough
(Tree?)Stink Bug (Brochymena
quadripustulata) on a bulletin board at Mason
Farm Biological Reserve, Orange County, NC, 11/14/07. It hides
easily on tree bark, unlike in this setting, a bulletin board. |
Rough Stink Bug
(Brochymena arborea),
Durham, NC, 11/9/10, on a painted wall, with some peeling of the paint
evident. |
(Copes?) Gray Treefrog
(Hyla genus),
Durham, NC, 10/13/08, on the rim of a brown
plastic garbage can. This is a normal, healthy frog. During
droughts, these frogs jump into rain-collecting containers, swim around
and leave without difficulty. But they do stand out in this
environment! |
Common Buckeye
butterfly (Junonia coenia), on a car at Freeman Park, Carolina Beach, NC, 10/19/05.
The beach is no place for this butterfly, which has the deep brown color
of mid-winter fallen leaves. |
|
Sometimes camouflage works against the animal's
interest, most notably with dark gravel pavement.
|
|

Blister Beetle
(Lytta aenea), probably not in great shape. Despite the red legs,
it's not easy to see and risks being stepped on. |

Müllerian Mimicry:
they are dangerous and let you know it
Actually, this is the real article: warnings given by these
colors and patterns should be heeded. It's not really mimicry, but that's
the official term!
The
insects (wasps and bees) shown below announce with their yellow-and-black stripes that they
possess venomous post-abdominal stingers, and they
are telling the truth.

Crablike Spiny Orb
Weaver (Gasterocanthis cancriformis), Carolina Beach State Park, New
Hanover County, NC, 6/23/06. A little different: spikes and no stripes. |
Zebra Longwing (Heliconius charithonia).
Across the street from the East Campus of Duke University, Durham, NC,
10/4/04. Its natural habit is in the tropics, so its mimicry is
probably less effective here, as the apparent bite out of the left wing
suggests. |

More Müllerian
Mimicry: red and black, but not friend of Jack
Red or orange with black is a warning of
poison. All of the below, as does the Monarch Butterfly, eat the
alkaloid-rich milkweed family members, which give them a bitter taste.

Like the milkweed-eaters, these animals are genuinely
poisonous, but they inject venom with bites or stings.

More
Batesian Mimicry: red and black (sometimes with white)
There are many insects and some
spiders in this group. In the first row, we see the fancy ones: the first
two can look green instead of black in direct light. The others sport
multiple white stripes.
Since there are so many red and
black insects, this might also serve as an abridged identification guide to this
large, confusing group.

Flea Beetle
(Disonycha genus, Alticini tribe), Durham, NC, 4/19/06. This beetle was
visiting a dandelion. |
Burdock Beetle (Leptinotarsa juncta). 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. It is an herbivore, but not a crop pest. |

Crablike Spiny Orb Weaver
(Gastrocantha cancriformis), Carolina Beach State Park, New Hanover County, NC,

access, 4/4/07 |

Spots, whether red on black or vice versa, are
a common sight. All of these animals are designed to ward off predators:
they are all herbivorous except for the Ladybug Beetle, whose black-spotted red
expanse towers, out of sight, over its tiny aphid prey.

apparent reason. An early instar. |
Early instar leaffooted bug nymphs! Johnston Mill Nature
Preserve, Orange County, NC, 5/31/07. They grow up to be brown,
but late instar nymphs are gray. |
Red-shouldered Bug nymph (Jadera haematoloma), Raulston

Adult velvet mite (Trombidiidae family), Eno River State Park, Orange
County, NC, 10/26/09. This predator (a former parasite as a nymph) was
unusually large for its type at about 2 mm long. |
Adult Golden Net-winged Beetle (Dictyopterus aurora),
American Tobacco Trail (Mile 5), Durham, NC, 2/26/09. A fairly
large, showy beetle, it's anomalous in this group. |
|
|
|
|
|
And this young animal's species is unique here,
its members containing tetrodotoxin, the same poison that makes the notorious Japanese puffer
fish so deadly, but this does not protect them from certain wily (and dexterous)
predators, according to Eisner (2003).
|
|
Red-spotted Newt (Notophthalmus viridescens), red eft stage,
Appalachian Trail, Macon County, 8/18/04. Red spells "poisonous"
in nature's lexicon, but when this baby newt grows up, it'll have to rely on its wits to survive,
since it'll be mostly brown with a few small red spots. |

These three red-and-black arthropods all mimic
one another; none attacks humans (but please don't eat them in any case...)

Grapeleaf Skeletonizer (Harrisina americana),
outside at the Museum of Life & Science, Durham, 6/6/05. This is a
notorious agricultural pest. |
Here is a very miscellaneous group that also would
make easy prey without their distinctive colors. Although Boxelder Bug
nymphs are lively, even they are handicapped by their winglessness.

Very well-fed Wheel Bug (Arilus cristatus) nymph, Durham, NC, 5/10/08.
This formidable creature can stand up to anything but droughts. |
Boxelder Bug (Boisea trivittata) nymph, Durham, NC, 5/6/09 |
Adult Boxelder Bug (Boisea
trivittata), Durham,
NC, 11/18/07. Now that it has wings, this bug doesn't need nearly
as much red! |
