This black beetles are carnivore at larvae stage but after they become adults, they change themselves as herbivore!

@dipterrah submittd: found this strange fella swimming in a pond in Greenville, North Carolina. it was about 1-2 inches maybe, and burrowed into the dirt after i snapped these pics

A precious long water pal! Looks like a giant water scavenger beetle larva. Adults look like this:

Bug of the Day

Still amazed that this photo was at all in focus because the beetle was So. Darned. Tiny. This is a Hydrochus sp., a new genus for the yard. I was trying to find out more about the genus, since the name and family (Hydrophilidae) suggests they are aquatic. From what I can glean from the internets, the larvae are aquatic but the adults are not, and the genus feeds on vegetation and/or detritus.

#1455 - Fam. Hydrophilidae- Water Scavenger Beetle

A fairly sizable insect larva I found in a puddle at the Alison Baird Flora Reserve, as the lower-lying areas were filling up with ground water last year.

Water Scavenger Beetles range in size from 1mm to over 50, and may be found in water films, water-filled cavities in plants, waterways, lakes, and ponds, or even terrestrially or in decaying matter, depending on subfamily and species. 

Most Hydrophilid larvae are voracious aquatic predators, despite the common name of the family, and some are predators of mosquito larvae, while others specialise in snails. They do their digestion externally, and since most genera lack channeled jaws they have to lift prey out of the water to feed.  Some larvae respire through the cuticle, or via tracheal gills. In other species the last spiracles open into a respiratory cavity which is closed when submerged.

Adults, on the other hand breath via a very small air store under the elytra where the spiracles open. This air store connects with an air film covering a large area of the beetle’s underside, which acts as a compressible gill held in place by water-repellent hairs. For gas exchange, the beetles break the water surface film with their short, clubbed, water-repellent antennae, forming a channel between the atmosphere and the air store. Unlike other water beetles, Hydrophilids are generally not very good swimmers, and like their young, clamber over submerged vegetation.

Adults are frequently attracted to lights when flying at night, and many can produce sound, either in reproductive displays or when disturbed. Females produce silk cocoons or cases that contain the eggs, with some species carrying the cases under the abdomen, and others building free-floating rafts.

when i was little my friend had just dance for the kinect and one of the songs was one that the slugs in flushed away sang and it was a really long and tiring song and im an out of shape bitch and i was in physical pain for the last half of it and all i could see in my head were those dumbass slugs and your icon made that memory resurface

I’m very sorry that I caused a painful memory to come back, but also glad that the cinematic masterpiece Flushed Away has made a lasting impression on so many lives. Always happy to help 👍
