However for dytiscids
as reported for 31 July (Table 1), warm ambient temperatures may not directly influence their physiology because of their aquatic habitat.
The number of replicates for each types of predators were: gerrids (12 replicates); hydrometrids (16 replicates); veliids (12 replicates); notonectids (18 replicates); and dytiscids
Three hundred and seven collections were made throughout Tennessee for a total of 11,023 specimens and 101 species of dytiscids

(Coleoptera: Dytiscidae) and effects of fish predation on upper littoral zone macroinvertebrate communities of Arctic lakes.
The non-mosquitoes invertebrates found in the stream pools along Jaribuni River included Gerrids, Hydrometrids, Notonectids, Naucorids, Dytiscids
, Libullids, Coenagrionids and tadpoles.
Significant changes in prey regimes during development of larval dytiscids
should be reflected in the morphology of the cranium and/or its appendages.
These larvae have well-developed series of natatory sensilla characteristic of nektonic dytiscids
with the distribution of the spiniform sensilla corresponding to patterns of previously described larvae of Dytiscinae.
paugus (Fall) as the species of record for Georgia (as Hydroporus) with collection data indicating that these dytiscids
have been collected infrequently in only a few counties.
that feed extra-orally have deep medial mandibular channels for delivery of digestive enzymes into and the ingestion of liquefied materials from prey.
Chaetotaxy of first instar dytiscids
provides a number of characters employed in systematic studies.

In addition to Dytiscus carolinus, a number of other dytiscids
were using the marsh as a breeding site.
