Aquarium's deep-sea isopod hasn't eaten for over four years
A creature known as “the scavenger of the deep” has surprised its keepers at an aquarium by “fasting” for more than four years. The giant male isopod, called No. 1 to distinguish it from the two other giant isopods kept at Toba Aquarium in Mie Prefecture, last ate in January 2009, when it was fed a whole horse mackerel. .../...

The origin of winged insects (Pterygota), one of the planet’s most diverse lineages of organisms, is assumed to lie in the Devonian, but as an extremely sparse fossil record impedes our understanding of their early diversification, any well-preserved insect fossil from this time would be particularly valuable. .../...

We discovered that nectar guides made legitimate visits more efficient for bees than robbing, and increased the relative frequency of legitimate visits, compared to flowers lacking nectar guides.
This study is the first to show that beyond speeding nectar discovery, a nectar guide pattern can influence bees’ flower handling in a way that could benefit the plant.

Well the mystery is I don't know what species of Sminthurides this is. I found this one on the same stick as the Ceratophysella denticulata. It was found by the edge of a very soggy and muddy field.

Like humans, insects communicate with each other by “telephone” and can even leave messages, according to Dutch researchers. No special electronics are needed because the bugs literally use green technology – plants – to communicate.

I spent time with researchers and growers who are working to stop this bacterial illness, which leaves fruit green and bitter and kills trees. Known as huanglongbing (HLB) -- Chinese for yellow dragon disease -- it is caused by bacteria that hide in the salivary glands of invasive insects known as Asian citrus psyllids. The pests arrived in the U.S. in the late 1990s and have spread the disease by injecting germs into plants as they feed on sap from their leaves. There is no cure for the disease.

The Arctic Springtail is a small, mite-like creature that lives under rocks in the Arctic, where temperatures can get as low as -20°C.
During winter these small creatures completely dry out, pushing all of the water out of their bodies until they could be mistaken for a 'crumpled up crisp packet,' says Dr Melody Clark from the British Antarctic Survey, co-author of the study.

There are many types of bees in this world, but the average person can probably only name two or three – usually honey bees and bumble bees – in addition to wasps and hornets, which are not bees. In fact, there are almost 20,000 bee species housed within Superfamily Apidae, and there are many unidentified, and as yet, unclassified, types of bees out there.

« We humans share our space with lice, bedbugs, fleas, and other vermin, but we’re not the only societies plagued by little hangers-on. Ants contend with an astounding array of body mites. I bring this up because Insectes Sociaux recently published a thorough survey of which mites live on which parts and which castes of which ant species across an entire ant fauna. »

In this study, we investigated the predatory behavior of the ant Azteca andreae which is associated with the myrmecophyte Cecropia obtusa.This group ambush hunting technique is particularly effective when the underside of the leaves is downy, as is the case for C. obtusa.In this case, the hook-shaped claws of the A. andreae workers and the velvet-like structure of the underside of the leaves combine to act like natural Velcro that is reinforced by the group ambush strategy of the workers, allowing them to capture prey of up to 13,350 times the mean weight of a single worker.
