Platypus crab
Fossil crab reveals a new branch in the tree of life
Abril 25, 2019
By taking on characteristics from another, younger stage in its life-cycle, this fossil crab was probably able to adapt to new conditions.
Hormone Hang-Ups
Parasitoid Wasps may turn spiders into zombies by hacking their internal code
Abril 26, 2019
Parasitoid wasps lay their eggs on a spider’s back. This team proposes that by injecting the spider host with the molting hormone, ecdysone, the wasp induces the spider to make a special web for the wasp’s pupa.
Parents Unknown
Mysterious Larvae Discovered in Panama’s Two Oceans
Mayo 14, 2019
These ghostly larvae float freely in seawater, while their parents live on the sea floor and usually go undetected. Genetic studies of larvae provide clues that there are more species to be discovered
Pheromone talk
The queen gets to keep her daughter
Mayo 23, 2019
Why did some bee species become social, while the majority have remained solitary? On Barro Colorado Island, a bee that adopts both strategies interchangeably, may unlock the evolutionary origins of sociality in insects
Empathy
Insects need empathy
Julio 03, 2019
Yves Basset, who heads insect monitoring efforts for the Smithsonian ForestGEO program and Greg Lamarre, from the University of South Bohemia, present immediate, science-based actions that mitigate insect decline.
Is evolution predictable?
Butterflies take different paths to arrive at the same color pattern
Noviembre 14, 2019
Unrelated butterflies may have the same wing patterns. These patterns warn off predators and help suitors find the right mate. But if wing patterns in each species evolved the same way, knocking out an important gene should have the same effect in both. Carolina Concha and her team discovered that knocking out the WntA gene results in different effects in co-mimics, so the two species evolved the same pattern via different pathways.
A Fearless jewel
NOT a Bird Dropping
Enero 24, 2020
The discerning eye of staff scientist, Annette Aiello, observed the fearless behavior of an iridescent insect resembling a bird dropping containing embedded, blue seeds.
Male or female
How does an intersex bee behave?
Marzo 10, 2020
A collaborative effort at Barro Colorado island described the daily rhythm of a rare half male-half female bee
Old Genes, New Traits
Recycling old genes to get new traits – How social behavior evolves in bees
Junio 10, 2020
Researchers learned from some unusual sweat bee species on Barro Colorado Island, Panama, how the sophisticated division of labor in highly complex insect societies can arise from humble beginnings.
