Inside the World of the Common green darner

Question 1 · multiple choice

Which field camp would place a researcher closest to the natural home of a Common green darner?

forests, bamboo thickets, wetlands, and farmland edges cold rivers when young and spawning, open North Atlantic as adults lowland tropical forest, swamp forest, and forest clearings ponds, marshes, lakes, and nearby open air

Question 2 · multiple choice

Which food tray most closely copies what a Common green darner normally finds in nature?

small flying insects as adults and aquatic prey as nymphs squid, fish, and carrion taken from the sea surface insects and small vertebrates zooplankton and tiny drifting animals filtered from water

Question 3 · multiple choice

Which activity schedule best describes a Common green darner?

does not follow normal daylight cycles in permanent darkness hunts by day in warm conditions hunts mostly by day near its burrow mostly forages at night

Question 4 · multiple choice

A Common green darner must travel through its habitat. Which movement strategy does it actually use?

swims with body waves and walks slowly on tiny limbs walks, swims briefly, and strikes prey from close range flies forward, backward, sideways, and can hover walks on land and climbs trees but adults cannot swim

Question 5 · multiple choice

A Common green darner succeeds in its habitat partly because of which adaptation?

mucus and fine cilia carry trapped food toward the mouth large forward-facing eyes judge distance while silk provides a safety line a false thumb helps grasp bamboo while thick fur insulates the feet large compound eyes and independently controlled wings track prey in flight

Question 6 · multiple choice

A wildlife nursery prepares for a young Common green darner. Which developmental fact should guide the team?

eggs are inserted into aquatic plants and nymphs grow underwater a single infant usually remains dependent on its mother for years one pup rides on the mother’s back and its stripes align with hers two pea-sized eggs are raised by the female in a tiny flexible nest

Question 7 · multiple choice

A group-behaviour study follows a Common green darner. Which result should the team expect?

mostly solitary at sea but gathers at feeding or nesting areas adults often patrol territories while some populations migrate in groups often gathers loosely where overhead prey is common often gathers where organic-rich sediment is available

Question 8 · multiple choice

If Common green darner numbers fell sharply, which ecosystem service could be affected?

connects distant ocean food webs and brings marine nutrients to islands controls large night-flying insects controls mosquitoes and other insects in both water and air moves plankton energy to large marine predators and supports cleaning communities

Question 9 · multiple choice

Which defence strategy is actually used by a Common green darner?

warns with hood, growl-like hiss, and controlled strikes uses speed, camouflage, and deep pools uses chest beats, displays, and group protection before physical conflict escapes through agile flight and nymphs use a sudden jet of water

Question 10 · true false
