Latest Sphingidae Stories
When their favorite food isn’t readily available, hawk moths are able to switch to a different olfactory ‘channel’ in their brain, enabling them to learn how to find alternative nectar sources.
Instead of using visual cues or floral scents, some moths detect increases in humidity around flowers to see if it is worth further inspection, new research led by a University of Arizona entomologist has found.
In collaboration with colleagues from Portugal and Spain, researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, have developed an apparatus that automatically applies odors to an airstream, while filming and analyzing the behavior of insects simultaneously.
Columbine flowers are recognizable by the long, trailing nectar spurs that extend from the bases of their petals, tempting the taste buds of their insect pollinators.
In most animal species, males and females show obvious differences in body size.
University of California-Santa Barbara scientists say they have identified the genes that are responsible for changing a flower's colors. Professor Scott Hodges and graduate student Nathan Derieg said they studied red columbines pollinated by hummingbirds and white or yellow columbines pollinated by hawkmoths to document the evolution of such flowers in North America. They said their research indicates a color shift from red to white or yellow has occurred five times in that region. What is...
Most scientists who create models trying to understand the mechanics and aerodynamics of insect flight have assumed that insect wings are relatively rigid as they flap.
Scientists at UC Santa Barbara have zeroed in on the genes responsible for changing flower color, an area of research that began with Gregor Mendel's studies of the garden pea in the 1850's.
Moths need just the essence of a flower's scent to identify it, according to new research from The University of Arizona in Tucson.
Three species in the Acherontia genus make up the group commonly referred to as the Death's-head Hawkmoth. One species is native to Europe, while the other two are found in Asia. These moths are named for their unique skull shaped markings on their thorax and vividly colored abdomens. They are also capable to making loud noises if frightened. These moths will invade beehives for honey and will come and go unharmed because they imitated the scent of the bees. Females will lay green or...
The Hummingbird Hawk-moth (Macroglossum stellatarum) is a species of hawk moth with a long proboscis. It is capable of hovering in place, as well as making an audible humming noise. These two features make it look remarkably like a hummingbird when it feeds on flowers. The forewings are brown and the hindwings are orange. The wingspan is 50-58 mm. Adults may be encountered at any time of the year, especially in the south of the range and two or more broods are produced each year. They fly...
Hawk moths (or Sphinx moths) are moths in the family Sphingidae. They are some of the fastest flying insects, capable of flying at over 30 miles per hour (50 km/h). They have a wingspan of 35-150 millimeters. Some hawk moths, like the hummingbird hawk moth, hover in midair while they feed on nectar from flowers and are sometimes mistaken for hummingbirds, even in continents where hummingbirds are not found. The larvae of most species of hawk moth have a "horn" at the posterior end. Because...
