ABOVE A conehead katydid nymph
sits on a leaf. When adult, with fully
grown wings, katydids ‘sing’ by
rubbing a comb-like row of pegs
under the left wing on a plectrum-
like ridge on top of the right wing,
‘kay-tee-did’ being the onomatopoeic
representation of a common call.
LEFT A female Alpaida spider
cradles an egg sac. The silk igloo
hides the vulnerable eggs from
predators and parasitoids.
The mother will also remain on guard
to see off any potential enemies.
When they hatch, the spiderlings
will have to disperse quickly,
not only to escape their foes
but also to avoid cannibalism.
