MAINE CRANBERRY PESTS: (Place your cursor over an image in order to know what it is.  You can also look at the last part of your URL or web page address once you have clicked on an image and that will show you its name in many cases as well.)

Photo of several Cranberry Tipworm 2nd-instar larvae ('white' stage) (as seen through a dissecting scope) Two Cranberry Tipworm eggs - 6/13/2007 (marking the start of perhaps the 3rd-generation that year) Photo showing a Cranberry Tipworm fly (orange in color, which means it is a female; males are grey or black) photo of a Cranberry Fruitworm larva on a person's thumb, plus the remains of the cranberry from which it came, with lots of frass visible inside the berry photo of a Blunt-nosed Leafhopper adult resting on a sweepnet photo of a Blunt-nosed Leafhopper adult resting on the rim of a 12"-diameter sweepnet two separate closeup views (seen through a dissecting scope) of a Blunt-nosed Leafhopper adult Photo showing several False Armyworm caterpillars together, next to (and some of them 'on') a cranberry upright for scale purposes Photo of a mid-sized False Armyworm larva crawling on the edge of a US dime (shown for scale purposes) Photo of a False Armyworm caterpillar attached to a cranberry upright and feeding on one of its leaves photo showing a Blackheaded Fireworm larva (photographed June 18th in central Maine) Blackheaded Fireworm larva (photographed May 27th in central Maine) Blackheaded Fireworm larva (pictured here early July, 2005) picture of a Blackheaded Fireworm moth in the palm of a person's hand; they are very small a Blackheaded Fireworm moth (June 21st, 2010) (central Maine) a Blackheaded Fireworm moth (June 21st, 2010) (central Maine) photo of a Hill Fireworm larva (photographed June 20th - central Maine) photo of a Gypsy Moth caterpillar beside a Canadian penny for scale purposes fairly close picture of a cranberry weevil against a backdrop of the terminal leaves of a cranberry upright Photo of a Cranberry Weevil on the edge (frame) of a sweepnet (photographed July 20th in central Maine) Picture of a Cranberry Weevil (closeup) on a cranberry blossom (photographed July 6th) Close view of a cranberry weevil, laying on its side, right next to a small portion of a US penny (for scale purposes) photo showing several Cranberry Weevils (crawling on the rim of a baby food jar) (photographed in early July) 3rd photo of a cranberry blossomworm larva feeding on a cranberry upright in a cranberry bed Picture of a Horned Spanworm larva (Nematocampa resistaria) next to a US nickel coin photo of a Green Spanworm larva, photographed in early July 3rd photo of a Chainspotted Geometer (type of spanworm), at the tip of a cranberry upright; photographed in July (in Maine) photo of a Chainspotted Geometer larva (photographed mid-June) (shown on the rim of a sweepnet) a Chainspotted Geometer larva (June 21st, 2010) photo of a spanworm named Big Cranberry Spanworm (photographed July 10th) (a master of camouflage - it looks exactly like a twig in the picture) photo of a Humped Green Fruitworm, with its hump on the left end and its head is on the 'right' end photo of a Humped Green Fruitworm moth, at rest (moth was reared through to the adult stage from one of the caterpillars) Photo of a Red-headed Flea Beetle resting on top of a Maine cranberry - Late August 2009c Red-headed Flea Beetle (closeup view) (head has a slightly reddish tint visible when you look closely or if the light catches it properly) Red-headed Flea Beetle (perched on the edge of a sweepnet) (late August 2009) Photo of two aphids (their feeding is damaging but their numbers are seldom ever worrisome in a cranberry bed but occasionally you may encounter isolated patches of them which can be alarming at first) Cranberry Sawfly larva (hind end will frequently curl around, giving the larva a C-shape design; they are also frequently slightly moist/shiny in appearance, and have two little black spots for eyes) photo showing several sawfly larvae (and a note about the 'C-shape' to their bodies - they often curl their hind end around in this fashion)

BENEFICIALS:

photo of a Green Lacewing adult perched atop a cranberry upright; this is considered to be a beneficial insect as it is a predator on many other insects Picture of a species of Syrphid Fly; adult (Toxomerus marginatus) which is parasitic on Cranberry Tipworm maggots Another photo of the Syrphid Fly, Toxomerus marginatus (family: Syrphidae) (seen here in early July of 2008) A solitary ground-nesting bee (6/22/2007 - Etna, Maine) Yellowjacket (probably either the Common Aerial Yellowjacket - Vespula vulgaris - or Eastern Yellowjacket - Vespula maculifrons) (maybe even an Aerial Yellowjacket, Dolichovespula arenaria) European Honey Bee (Apis mellifera) (obviously a beneficial, but it seemed only fair to recognize it here) 2nd photo of a honey bee gathering pollen in a Maine cranberry bed Bumblebee (Bombus species) coming in for a cranberry landing a Ground beetle/Tiger beetle in the family Carabidae or possibly Cicindelidae (These beetles are very fast, both in the air and on the ground, and are voracious predators) (pictured beside a US penny for scale purposes) a Ladybug Larva (June 21st, 2010) - they are beneficial, eating aphids, mites and other small-bodied insects they encounter. picture of a Ladybird Beetle (ladybug) two Parasitic Wasps (common name is Sword-stabbing Wasps) (a male and a female) A closer view of one of the parasitic Sword-stabbing wasps pictured at left


CURIOSITIES (cause very little or no harm at all to cranberries, but are sometimes encountered on the beds):

photo of a Crane Fly adult (adults do not feed and the larvae feed primarily on decomposing organic matter) Picture of a Mayfly, photographed in Etna, Maine 'spit-like' froth secreted by a Spittlebug larva (also called a froghopper larva) (seen here in Mid-June in central Maine) two Spittlebug (froghopper) nymphs, removed from their protective frothy 'spit' which is visible in the picture at left Springtails (Collembola) (also called Snow Fleas but they area not fles; they are very tiny, primitive hexapods that recently are no longer even considered to be insects) (each dark speck is a Springtail - view the next photo as well for a closer view of them) Springtails (Collembola) (closer view) (They are decomposers that are found virtually anywhere there is wet soil, and frequently anywhere where there is leaf litter or other decaying material) Type of Leaf beetle called a Calligrapha beetle (Family Chrysomelidae) (This one is likely Calligrapha multipunctata, which feeds on willow) Shore Fly (Ephydridae family) genus Scatella (pictured here 5/31/2007) (They live in wet areas and both the adults and the larvae feed on algae; they can occur in large numbers so are sometimes very numerous in your sweepnet)
