If you study the sucking part and Neck part its different. Legs are also not hairy, so its little different, need help of local zoologist.
Good work Dan. I am not nature specialist, but I am satisfied with my one observational satisfaction is accepted.
I have added all the photos I have of this to help with ID
I checked some mating pics of these bugs, observed male and female has little different shape. Dan need to find need spotting of this bug. Neck part and sucking part is most important to define species. These long Greek names contains their type of bugs body parts. I get this information just checking accurate specie of this bug. Dan please take more pictures in more different angles of this bug.
You're on the right track with the Reduviidae. I'm pretty sure that it's an assassin bug. It's not Dysdercus koenigii for two reasons. 1 - This is a South American species, while Dysdercus koenigii is an Asian species. 2 - The body plan is different, more akin to the seed bugs or fire bugs. So, we can rule that one out. It's definitely not a stink bug either, so we can rule out the Pentatomidae. I think Lars is on to something with Rhynocoris and the stripe pattern. I've searched around online, but I'm not having much luck finding similar-looking Rhynocoris pictures. It looks remarkably like a milkweed bug, which is pretty sweet. I'll have to do some more research later, but these are the families I think this one is most likely to be in: Reduviidae Coreidae Alydidae
Rhyconoris bugs are from the family of the Reduviidae, Superfamily Cimicomorpha, Suborder Heteroptera...so, i still believe we're on the right track with the Reduviidae
Its matching as Cotton pest...No need more.. http://en.wikipedia.org/wiki/Pentatomidae http://www.google.co.in/search?sourceid=chrome&ie=UTF-8&q=Forest+bug Lars also comes to Pentatomidae
a step closer, i guess: I think its a part of the Rhynocoris family...they basicly have all that "zebra" pattern on the sides of the body-ends.. (http://www.koleopterologie.de/heteroptera/)
Yes its Cotton pest..due to change in colours, size in different continent as per atmospheric habitat some change is there...They tough to classify properly.
thanks Ashish, the photo at the top of the link looks a lot more like it, I think we're on the right track now....
I find similar shape at http://www.agricultureguide.org/cotton-pests-that-deserve-the-royal-stink-eye/
you're welcome, Dan....I'll keep the eye on it.
thanks for all the work you guys put into this spotting. Lars, it does look similar to the link you provided, but like you said, I am looking for the exact species. Ashish, it does look like it could be a member of the Coreoidea family. the search continues.....
http://en.wikipedia.org/wiki/Coreoidea
Its original family is as following link http://en.wikipedia.org/wiki/Pentatomoidea
http://en.wikipedia.org/wiki/Reduviidae
Looks more like some kind of Milkweed bug to me but they are mostly North American, so I'm not 100% positive. http://akdavis.myweb.uga.edu/Undergrads/milkweed-bug.jpg
I know there are some differences, Ashish. But it's obvious that's some kind of assassin bug - the entire shape of the corpus is telling...so we got to put our focus on that family.
Lars its kind of some different bug you are telling.. in your reference I obsereved its legs are hairy..wings closed with different style..so not matching...Neck to head also not matching...see my spotting its almost same like Dan..
It's definetely an Assassin Bug or Reduviidae (lat.) - but i think Dan wants to know the exact species. thats what i found so far: http://www.geo.de/GEOlino/natur/tiere/53221.html?t=img&p=7 It says its a Assassin Bug (Raubwanze), which habitat is in Costa Rica. (Though i figure not the exact pattern in comparison of both pictures - but i think it's pretty close...maybe a question of the position of the wings and how they're correctly folded?)
http://www.google.co.in/search?q=Red+Silk+Cotton+Bug&hl=en&prmd=ivns&source=lnms&tbm=isch&ei=EYO4TfaFFozsrQev-OjdBA&sa=X&oi=mode_link&ct=mode&cd=2&ved=0CA4Q_AUoAQ&biw=1280&bih=737
the colour changes are very little in same species in different continent. Do not worry all shape and colour combination at legs, strings, wings almost matching to my spot and Nepal website..also see images in google search...I see..some matching to ur one.
I see it and thanks for the suggestion but I'm still not convinced. the red silk cotton has red legs, mine has all black legs and the red doesn't have the round edge abdomen with the black and orange striped markings that mine has
Also see http://www.pbase.com/bmcmorrow/image/90486097
I found it in your 'spottings' and compared the photos. upon close inspection, I don't think its the same species
Actually I have it in my spottings..and refered my nature specialist friend Anand Pendharkar. I am started search it now...
ok, can you send me a link with a photo? the ones I see on google images don't quite match up
Its Red Silk Cotton Bug
no, sorry...but i favorized it; so i'll keep an eye (and id) on it ;)
damn, dan...you're a lucky man. :) awesome species.
