hymenoptera
milhayser | June 4, 2012By gluing radio chips to the backs of 800 honeybees, researchers proved that Neonicotinoid pesticides interfere with their behavior. Greg Laden reports that bees exposed to the common aphid-killer "forage abnormally, have 'olfactory memory' problems, are easily disoriented and become poor learners." Fewer of them return to the colony. Laden observes, "One thing that strikes me as especially interesting here is that many bees don't make it back over a fairly long period of time even under normal conditions, and that some bees stay out overnight!" Another likely contributor to Colony Collapse…

The life cycle of a honey bee is presented in this video as an example of complete metamorphosis, the development of an insect from egg to larva, then pupa, then adult. Moths, butterflies and wasps also develop with complete metamorphosis. Some aspects of beekeeping are also discussed in this video.

Welcome to Circus of the Spineless! This is the migratory blog carnival that specializes in all things spineless, and the contributions that you'll find here range from essays and photoessays, to photographs with some accompanying explanatory text and even a few videos. This blog carnival has seen some scary times in its recent past where it almost went extinct, but thanks to some friends of mine who are much more expert in spineless things, it was revived after I made a bunch of noise about…

Common Eastern Bumblebee, Bombus impatiens.

The Bumblebees, Bombus species, are among the most popular of all insects. Their black-and-yellow fuzz, large round bodies, and bumbling, buzzing flight make them appear almost cuddly, almost like the "teddy bears" of insects. I have many childhood memories of watching these appealing gentle…

For contrast, here's a photo of a wasp in the same genus taken with my standard Canon macro gear:

Atta texana queen and worker
Ant queens are those individuals in a nest that lay the eggs. They're pretty important, of course, as without reproduction the colony dwindles and disappears.
Understandably, ant-keepers have an interest in making sure their pet colonies have queens. Conversely, pest control folks trying to get rid of ant colonies need to be sure that they've eliminated queens. Whether your interest is live ants or dead ants, I'll give some pointers in this post for recognizing queens.
In many species the difference between workers and queens is obvious. Consider the…

This streaming video is a fascinating close-up interaction with a wasp by the photographer, who goes by the name Lucasberg. To get these amazing shots, he used a 180mm SLR macro lens. The photographer says the video is a little shakey because he was balancing on the handrail of his porch and could only use 1 tripod leg while filming. [1:06].

Eusociality, or "true social behavior", is the most extreme form of cooperative sociality known. Due to its seemingly altruistic nature, eusociality has provided many interesting challenges for evolutionary theory. Eusociality, as exemplified by ants, bees and wasps, is…
