Drop Your Weapons!
Autotomy, the shedding of a body part, reveals the hidden cost of conflict
November 16, 2018
Not only does it take energy to make weapons, it may take even more energy to maintain them. Because leaf-footed bugs drop their legs, it is possible to measure how much energy they allocate to maintaining this appendage that males use to fight other males.
Cloud habitat
Mysterious cloud forest bees and their microbes - Part I
April 08, 2019
Three adventure-seekers meet in the clouds, each with their own reasons to learn more about mysterious jewel-like bees.
Hormone Hang-Ups
Parasitoid Wasps may turn spiders into zombies by hacking their internal code
April 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.
Pheromone talk
The queen gets to keep her daughter
May 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
July 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
November 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
January 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.
Old Genes, New Traits
Recycling old genes to get new traits – How social behavior evolves in bees
June 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.
Insect societies
Can social bees and ants teach us the pillars of sustainable societies?
June 18, 2020
STRI staff scientist and evolutionary biologist Bill Wcislo discusses the foibles of social bees and farming ants and the evolution of their behavior in changing environments. In a time of crisis, what can we learn from these insects about their highly efficient public health care systems?
