I'm looking for recent dive/fishing reports of the Radford. If you've been there in the last year or two, I'd like to hear what you found. In particular, where is the stern now? I can find no reports since 2012.
New Jersey Scuba Diving
Insects are almost completely lacking in the marine environment. I recall something about salt water having a very bad effect on their lungless respiratory system ( although this does not affect spiders. ) Insects are quite common in freshwater environments though, both as larvae and adults. A little digging can turn up myriad types, but be careful, some of them can bite very painfully.
These are all known as "true bugs", as opposed to beetles, flies, ants, etc. Both the larval and adult stages are aquatic, although only the adult stages are shown here. All may be found swimming or clinging to underwater plants, and must surface to breathe. All are also strong fliers that are attracted to lights at night, and have a painful and poisonous bite. Giant Water Bugs are known to feed on small fishes.
Skims along on surface of water. Flies well, but does not dive.
Not a true scorpion, but has a very painful bite.
Giant Water Bug
Beetles are differentiated from bugs by having the first pair of wings developed into armored shields, which protect the second pair of wings and the soft body. They can still fly with their second pair of wings, which fold up out of sight when not in use. Only adults are shown here.
Water Scavenger Beetle
Adults feed mainly on plant matter; larvae are carnivorous. Other diving beetles are predatory.
Whirligigs are generally found skating along the surface, although they are also good divers and fliers.
Many insects which are terrestrial as adults have aquatic larvae. Notorious among these are mosquitos. Most aquatic insects have aquatic larvae.
Caddisfly larva build tube-like cases of sand, sticks, leaves, or other material.
larva to 2 "
Dragonfly - Adult & Nymph
larva to 1 "
adult to 3"
The clumsy-looking Dragonfly larva is actually a fierce predator, with protrusible jaws like something out of "Alien". Adults are often seen buzzing around ponds and lakes.
Dragonflies are anything but tame - this one was blown out to sea and exhausted
Size: to 10"
Notes: It's not a nice thought, but there are leeches in our fresh waters, and in marine habitats as well. The species shown is one of the largest and most attractive, if you can say such a thing. It feeds exclusively on vertebrate blood - a good reason to wear a wetsuit, although I've never encountered one. Leeches are actually worms, not insects, but ...
I make no claim as to the accuracy, validity, or appropriateness of any information found in this website. I will not be responsible for the consequences of any action that is based upon information found here. Scuba diving is an adventure sport, and as always, you alone are responsible for your own safety and well being.
