Insects make up more than half of the known animal species on our planet and they can be found in all kinds of habitat and feed on all kinds of nutrients. They can even be used in evidence in court cases. So we are talking about forensic entomology.

The queen honey bee is genetically identical to the workers in her hive, but she lives 10 times longer and - unlike her sterile sisters - remains reproductively viable throughout life. A study from the University of Illinois sheds new light on the molecular mechanisms that account for this divergence. The study appears in the online edition of the Proceedings of the National Academy of Sciences.

What could be more harmless than a bundle of firewood? Depending on where it came from, it could be a Trojan horse for emerald ash borers. "If we could get the word out to citizens and businesses not to take firewood out of quarantined areas, we could contain the infestation of the ash borer," said James Appleby, entomologist at the University of Illinois at Urbana-Champaign. It is currently against the law to transport firewood out of a quarantined area and offenders are saddled with hefty fines.

The discovery of a 100-million-year old bee embedded in amber -- perhaps the oldest bee ever found -- "pushes the bee fossil record back about 35 million years," according to Bryan Danforth, Cornell associate professor of entomology.
