Here's the step-by-step checklist for this leafhopper nymph's blastoff:
✅squirt a little honeydew
✅tuck the front legs
✅hold a statue pose all the way into outer space

New #siliceousplants paper out in @Plants_MDPI led by @thehungrybug with @ScottJohnsonLab. We found that silicon acts as a direct defence against chewing herbivores by altering the morphology of physical defence structures, not leaf mechanical traits.

Have you got a few minutes to channel your inner possum and see if you can tell the difference between Australian mistletoe leaves and those of their hosts? Play the game here:

If you enjoy the flavor of hops this #PhytochemicalFriday, you're tasting isohumulones, products of a hop chemical (humulone) as it degrades during brewing. They provide hops a characteristic bitter flavor. Their parent, humulone, seems to act as an antiviral and antimicrobial.

Happy #PhytochemicalFriday from #PAGXXVIII #PAG2020! Today: Aconitine: deadly poison from Aconitum spp. (aka Monkshood / Wolf's-bane) that features in modern mysteries and literature from Ancient Rome (Ovid). The alkaloid binds sodium ion channels & interferes with neuron firing.

This week I want to show you how beautifully diverse caterpillars have evolved.
Which one is your favorite?

Excellent talk by @thehungrybug at #JointAusBio19 on alkaloid defences as affected by plant silicon. Really cool interplay and interaction between resistance mechanisms

@rvandegeer gives a 5 min speed talk at #JointAusBio19 explaining how interactions between silicon and osmotic stress affect herbivores. Herbivores suffer from both; thicker leaves and physical defences?

I’ve come across quite a few people who scream when a moth flies at them. So for anyone with a moth phobia (Mottephobia) here is one all tucked up sleeping 💤 on a eucalypt leaf 🍃 in my back yard. Not so scary #eyelashes #moths #lepidoptera #mottephobia
