Latest Beetle Stories
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae.
University of Alberta researchers are closing in on finding an effective bait to get ahead of the destructive spread of mountain pine beetle, which is now killing not only lodgepole pine forests, but jack pine.
The bottomless pit of insect biodiversity has yielded a treasure trove of new species of jewel-like clown beetles.
Climate change affects forests across North America – in some cases permitting insect outbreaks, plant diseases, wildfires and other problems -- but Dartmouth researchers say warmer temperatures are also making many forests grow faster and some less susceptible to pests, which could boost forest health and acreage, timber harvests, carbon storage, water recycling and other forest benefits in some areas.
A new University of Colorado Boulder study indicates drought high in the northern Colorado mountains is the primary trigger of a massive spruce beetle outbreak that is tied to long-term changes in sea-surface temperatures from the Northern Atlantic Ocean, a trend that is expected to continue for decades.
A new study has found the mating behaviors of various insects change to avoid making themselves vulnerable during inclement weather.
Previously unknown to science leaf beetles modify and use as shelter the holes in leaves of their host plants made by other beetles
Hidden in the thick foliage of tropical forests a subfamily of colorful beetles hides the secrets of the earliest stages of social behavior, showing explicit signs of maternal instincts and care.
Beetles, cockroaches, and ants will have a harder time walking on facades or air conditioners in the future - thanks to the bio-inspired, anti-adhesive surfaces
Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack rather than that of a chewing herbivore
The Scarlet Lily Beetle (Lilioceris lilii) is native to Europe but is now widely found in North America. Larvae damage cultivated lily and Fritillaria plants. Photo by Keith Edkins The beetle family Chrysomelidae, or leaf beetles is a family of over 35,000 species in more than 2,500 genera. Leaf beetles are recognizable by their tarsal formula and distinguished from long-horned beetles (family Cerambycidae) by their short, filiform antennae. Adult and larval leaf beetles feed on all...
PHOTO CAPTION: The common asparagus beetle Crioceris asparagi is an important pest of asparagus crops. Photo by Keith Edkins 2003 The Common Asparagus Beetle (Crioceris asparagi) is an chief pest of Asparagus crops both in Europe and in North America; asparagus is its only food plant. The adult beetles and the larvae strip the needle-like leaves off the asparagus fronds which deprives the plants of the ability to build food reserves for future years. They also damage the shoots, thereby...
Ladybirds, also known as ladybugs or lady beetles are a family, Coccinellidae ("little sphere"), of beetles. The name is thought to allude to the Blessed Virgin Mary in the Catholic faith. Ladybirds are found worldwide, with over 4,500 species described - more than 450 native to North America alone. Ladybirds are small insects, ranging from 1 mm to 10 mm (0.04 to 0.4 inches), and are usually yellow, orange, or red with small black spots on their carapace, and black legs, head and feelers. As...
The longhorn beetles (Cerambycidae) are a family of beetles notable for their extremely long antennae. These antennae are often as long as or longer than the beetle's body in fact. The family is large, with over 20,000 species described. Several are serious pests, with the larvae boring into wood, where they can cause extensive damage to either living trees or to wood in buildings; the house longhorn Hylotrupes bajulus being a particular problem indoors. A number of species mimic ants and...
The beetle family Chrysomelidae, or leaf beetles, is a family of over 35,000 species in more than 2,500 genera. Leaf beetles are recognizable by their tarsal formula and distinguished from long-horned beetles (family Cerambycidae) by their short, filiform antennae. Adult and larval leaf beetles feed on all sorts of plant tissue. Many are economically important pests of agriculture, for example the colorado potato beetle (Leptinotarsa decemlineata), the asparagus beetle (Crioceris...
