The list of susceptible invertebrates includes bivalves, odonates
(dragonfly nymphs), polychaete worms, isopods and amphipods, decapod shrimps and crabs, as well as native gastropods (Appleton et al.
hellerii (Maciolek, 1984), which are known to adversely impact native Hawaiian odonates
(Englund, 1999), Australian native fishes (Warburton and Madden, 2003; Morgan et al.
were collected from the shoreline around the pond by use of a large aerial net and identified using regional texts (Curry 2001; Glotzhober & McShafirey 2002).
We found that lotic odonates
in Illinois were more likely to be uncommon/rare than lentic species, a result also found by Korkeamaki and Suhonen (2002) for odonates
Lastly, there is ample, succinct information on the life history, ecology, taxonomy, morphology, and curation of Odonates
in the front matter.
are readily collected in the field; however, laboratory rearing and experimentation allows researchers to regulate environmental variables that are difficult to control in the field.
Hymenopterans (Grant 1959), odonates
(Hofslund 1977), and mantids (Carignan 1988) have also been reported to attack birds, especially smaller species such as hummingbirds (Trochilidae).
were found to be absent at St II while their presence was recorded at rest of the stations in the monsoon period.
That's probably the simplest way to distinguish the two forms of odonates
, but there are a few others apparent on up-close viewing: Dragonflies have three tiny abdominal appendages used for grasping during mating, while damselflies have four; and dragonfly forewings and hindwings have different shapes, while damselfly wings are similarly shaped front and back.
Also, the pond was patrolled by odonates
for the majority of the sampling season, but they were not captured by this method.
have an important role in the dynamics of aquatic ecosystems and are considered one of the main predators of the littoral zone of lakes (SOTO; FERNANDES-BADILLO, 1994; LOUARN; CLOAREC, 1997; MARCO JR.
On these ponds few odonates
were observed and no E.
