The real Tinkerbell: don’t mess with these tiny fairy wasps

Have you ever seen a fairy? They exist, and may very well be in your garden. But you would need a high-powered microscope to spot the dainty creatures.

Fairy wasps (family Mymaridae) are tiny, feathery-winged parasitoid wasps. They’re often called fairy flies, which is a misnomer. The Mymaridae family includes the smallest known insects in the world. Most species are less than 1mm long – smaller than the average pinhead.

A failed experiment: earwigs as pests and predators in fruit orchards

Field ecology experiments are fickle. Even with best laid plans in place, they can fail…Nature doesn’t follow sampling protocols.

When this happens, should you publish the results? Most people would say no, and I would generally agree. Failed experiments are different to negative results. The latter are important additions to the scientific literature, but the former have very limited use. The results of failed experiments will have limited value, depending on why the experiment failed and how many data points were left intact. But they can have some use as ‘what not to do’ baselines for other researchers. Continue reading

Killer wasps and climate change

We recently got into the Fortitude series screened on the ABC in Australia. (Spoiler alert, if you continue reading). The show started off really well, successfully holding our attention after the incomparable Broadchurch (no mean feat!). Fortitude also had the promise of being truly brilliant. Halfway through, Nordic Noir descended into the standard gratuitous gore that sends a show from well-crafted, thrilling narrative into sensational schlock. Plus some character dead-ends and ambiguous plot-lines loosened the knots holding up a tight story. But it is still definitely worth hanging out for the next series (i.e. not downloading early off iTunes or whatever you cheat with).

From the first episode, I had a theory that the series was based on a pro-environment message. A tiny community (about 800 people) in Arctic Norway, an unconventional setting for standard TV dramas, is plagued by secrets, lies and grisly murders. The community is a mining town, as well as an arctic research station, and the governor is planning to build an ice hotel to boost tourism. Oh, the juxtaposition of ethical quandaries!
