Where are water scavenger beetle found?
marshy freshwater ponds
water scavenger beetle, any of the approximately 3,200 species of the predominately aquatic insect superfamily Hydrophiloidea (order Coleoptera). These beetles are found swimming in marshy freshwater ponds throughout the world, especially in warm regions.
What do scavenger beetles eat?
The larvae prey upon small invertebrates such as insects and snails, but can also consume tadpoles and small fish (Cranshaw 2010). As adults, these beetles will scavenge on decaying plant material and detritus in fresh bodies of water.
Do Coleoptera have antennae?
They have threadlike antennae and long slender legs. These insects are very fast and often difficult to collect. Their agility and strong mandibles make them well-adapted for their predaceous life style.
How many species are in Hydrophilidae?
The beetle family Hydrophilidae contains 41 species in 20 genera in the Korean peninsula (Cho and Park 2010). For an ongoing study of Korean aquatic beetles, we collected and borrowed the hydrophilid specimens.
What is scavenger insect?
Scavenger insects are essential to the ecosystems in which they exist, as they clear away rotting flesh and vegetation. Scavengers are typically omnivorous, feeding opportunistically. Many animal orders include scavengers; from the largest big cats to the smallest insects.
Why is it called Coleoptera?
The name Coleoptera, derived from the Greek words “koleos” meaning sheath and “ptera” meaning wings, refers to the modified front wings which serve as protective covers for the membranous hind wings.
How Coleoptera are different from the other insect?
The main difference between a bug and a beetle is that a bug belongs to the order Hemiptera whereas a beetle belongs to the order Coleoptera. Furthermore, bugs are mostly plant-feeders that take a liquid diet while beetles eat a wide range of plant and animal materials.
What is hole scavenger?
Most photocatalytic nanosystems reported so far employ a hole scavenger: a sacrificial chemical which is oxidized in the photocatalytic process and thus removes the hole from the nanostructure.

How do you identify Coleoptera?
Appearance of Adults:
- Chewing mouthparts (sometimes located at the tip of a beak or snout)
- Front wings (elytra) are hard and serve as covers for the hind wings; meet in a line down the middle of the back.
- Hind wings large, membranous, folded beneath the elytra.
- Tarsi 2- to 5-segmented.
What is Scavenger photocatalysis?
Many molecules have been used as radical scavengers in heterogeneous photocatalysis; for instance, to scavenge the hole in the valence band, electron donor species such as oxalate and formic acid are employed. Alcohols, such as t-butanol and methanol, are usually applied to confirm the contribution of HO˙.
What is hole in photocatalysis?
When a photocatalyst is exposed to light of the desired wavelength (sufficient energy), the energy of photons is absorbed by an electron (e−) of valence band and it is excited to conduction band. In this process a hole (h+) is created in valence band.
Where do diving beetles come from?
Predaceous diving beetles are in the Family Dytiscidae (from the Greek for “able to dive”); with 4300 species worldwide (about 500 in North America), they are the largest family of aquatic beetles. Typically, they live in the shallow, still waters of lakes and ponds or in the pool areas of streams.
What do diving beetles do?
predaceous diving beetle, (family Dytiscidae), also called diving beetle, or true water beetle, any of more than 4,000 species of carnivorous, aquatic beetles (insect order Coleoptera) that prey on organisms ranging from other insects to fish larger than themselves.
