Posted: Sun Jun 29, 2008 12:16 pm Post subject: Giant Water Bug
I just read Andrews thread on Giant Water Bugs and thought I'd share that I'm trying my luck with them. I'm keeping one in a medium sized KK filled with water with a fake plant in it. Its eaten a roach so far (girlfriend won't let me feed it fish). I think they're pretty neat bugs!
Its hard to take pics through the water, but here it is.
They aren't related to mantids. They're closer to assassins since they are a true bug. Their feeding habits are interesting! Instead of just grabbing onto their prey and just eating it, they first grab it, bite it, wait for it to die and sink to the bottom, then go down there and start feeding! Its bite can kill a roach in a matter of seconds! I'd sure hate to be bitten by one... Here's one feeding on a roach.
I've been wanting to try those. I've heard they fly, though, and my husband isn't crazy about the idea of a big bitey flying thing potentially escaping in the house. Have you seen it fly? _________________ Mommy loves her little Monsters.
Yeah -- or if you keep them in an aquarium, just put a screen top on it. _________________ "Tarantulas are friends, not food" (but I bet they taste pretty good with butter and lemon!)
10x14x3 clear plastic tray like "enclosure". No lid needed all this time ...bugs caught on first or 2nd SCABIES hike!! I keep 3/4" water in there ...or so. No substrate ..just a few stones and a couple loose roots. _________________

I had 3...peter, paul & mary. But, my female died when the water got really low while I was away (darn humidity dropped to the lower teens and just sucked the water dry) ...she got flipped over and it looked like she just couldnt get flipped back...like a screwed turtle.
They constantly produced young but I was never able to raise the young past 3rd or 4th molt. 1 got to about 3/4" and just freakin died. I gave it many honest attempts...trying different things.
From what Ive gathered ...read, observed, etc. Strong running water is the key when it comes to raising the young.

Adults do great together, but subs and young (even just a molt away from mature) will get munched by adults or siblings. _________________

Sorry to hear, Kyle. Do we know how long they typically live after their adult molt? (Maybe they normally just reproduce and die after their adult molt).
I hope you can find another one and try again sometime. That was a cool bug!

I was raised in Thailand, and I have eaten them. They are actually very good steamed (female). The male are aromatic (to the Thais at least), so they crush them up and use them to flavor up a type of chili sauce. Should anyone brave enough to try, see the below
O.K., now I have to tell my dad's "kochua" story. (Forgive me if I've told this one on scabies before).
My dad was in the Navy, and was stationed in Vietnam around 1966. While he was in Saigon he used to eat in a little hole-in-the-wall restaurant. One of his favorite dishes there included a spicy fermented dipping sauce. The restaurant owner didn't speak English, and my dad didn't speak much Vietnamese, but the owner managed to communicate that the dipping sauce that my dad loved so much was made with "kochua".
One day not long thereafter, my dad was walking through the lobby of a hotel when a bunch of porters and bellhops ran through the lobby chasing a large flying water beetle and yelling "Kochua! Kochua!"
;-)
(Apparently, Kochua brought a pretty penny in the marketplace if they could catch it!)
I would love to try the ones at Typhoon, but they are stuffed with Chicken and I don't eat Chicken... I wonder if they would make them without the Chicken?
My last one died ...it was either Peter or Paul (never could tell the 2 apart). _________________

I was luck enough to collect 3 last summer. One larger one and two juveniles. By the time I got home the larger one had killed the two smaller ones. I still have the larger one in a 10 gallon ¾ full of water, with some large rocks, live plants, and sticks and large pebble gravel across the bottom. I have it in with 5 or 6 sunburst diving beetles (Thermonectus mamoratus) and some small leaches that I have found.
With the pond grouping that tank I feed some frozen bloodworms, and freeze dried krill. I also collect damselfly larva and other aquatic inverts that never seem last long. If I don’t feed them for a couple days I come back and I am always missing a couple bugs.
This summer I am going to try to set up my 25 gallon tank (36x9.5x18) and put in a whole bunch of different aquatic insects and see what happens. I really want to get a nice tank of these guys and the T. mamoratus see if they will breed for continuously for me.

This summer I am going to try to set up my 25 gallon tank (36x9.5x18) and put in a whole bunch of different aquatic insects and see what happens. I really want to get a nice tank of these guys and the T. mamoratus see if they will breed for continuously for me.
The water bugs will devour all the other water insects ...anything that moves past them and if its handleable they eat. They will breed continuously but unless you have the numbers and right sex ratio your amphibian will only get occasional pig-out meals and once its full it probably wont get much of a 2nd or 3rd meal because the water bug nymphs will devour each other like some kinda sibling slaughterhouse and the adults will engorge the entire show and clean up whats left in the end. Its a seriously harsh social strategy ...once you hatch and start moving you'r food. Males will fight to protect the young on their backs but eat an occasional snack as they hatch.
Catch22 for the hobbyist is...separate them and they die. Still-water kills them though adults and sometimes sub-adults do well swimmin' in shat... the young NEED running water ...cool running water..with lots of hides and holds.
I believe its more than water purity though that may be a big factor. Changing water several times daily SEEMS to up the percentage of successful molts ...maybe 10% ...but it can be like a 50% death rate per molt plus mystery deaths in between for the first few and then after that you end up with one or few half inch bugs seemingly doing well then they die. (though ive had a bunch of hatchings that went extremely well first molt and somewhat ok during the 2nd)
Cool running water MAY be the big factor in a couple ways at least ways that ive been pondering. ...First temp of the water of course MUST affect their growth rate/feeding ...they may be speeding their way into each molt while sitting in room temps ..stuff may need time to catch-up..synchronize. If warm water softens up the molt and attachments too fast it may be pressing the issue and there is no helping force. Running water must put forces against the molt...it may help physically with the molting process and/or it may also stimulate the process. Also as the cool water slows their need to feed the running water has a chance to spread them around into separate pools downstream amping the survival rate ..most likely never high, but just enough. ...anyway..who knows..? The bugs know ..maybe. _________________
