Insect without compound eye?

[drkrishi]

Came across this strange Weevil like insect ~2.5cm long, in the garden. What was intriguing is that it has single eye not a compound eye like the rest of insect families. Here are 2 photo's I took using Canon 100 f2.8 Macro + 36mm Kenko extension tube.

With fill light from the front (Sigma 500 Super flash)

Any id of the insect is useful.

What an odd bug- excellent find and shots- are you certain the eye was not compound ?

I think its a Weevil, and it will have compound eyes :) ...

[johnkermit1]

i agree with above . . nice shots, and i think you just didnt get close enough to see the complex details perhaps.

Here is the closeup as close as I can get

and its 100% crop

But I still did not find the compound eye. I know that weevil's (if not all insects) have compound eyes :confused:

[johnkermit1]

perhaps the individual ommatidia are too small in this particular species.

Would the hexagonal catchlight indicate a compound eye? Looking really close at the eye I think I see individual cells.

I see what you are saying Nortelbert.

these links have some detail shown for weevil compound eye

Cool critter!!!- The "ant eater" appearance is bizarre----is that common for weevils?

[striving]

That thing is bizarre! I looked at BugGuide.net. Didn't see any weevils like this at all. Very cool critter!

I think I agree with that, johnkermit1 unless I have hit on a new Class inside Arthropoda ;)

i was upset about the katydid that i shot (my avitar), i was saying it had a solid eye, and i was wrong about that...if i had the raynox lens then, i would have been able to get the extreme closeup...and perhaps the detail i hoped for.

Really cool little bug. Anyone figured out what it is yet?

[jdm.squeek]

You know what they say, you find it you get to name it!

Hiya Krishna,

That's an interesting looking critter, I've had a look around & the only weevil that seems to be near yours could be a ' Giraffe weevil ' of some sort ??? if you follow this link

Cheers for now

Yes It looks very similar to New Zealand giraffe beetle which is different from the Giraffe necked Weevil (Trachelophorus giraffa) except the body spots do not exist. it is supposed to native of NewZealand I am far from it ;)
Here is further info I could gather
Lasiorynchus barbicornis, or the New Zealand giraffe beetle, is a straight-snouted weevil of the family Brentidae, endemic to New Zealand. It is New Zealand's longest beetle. Its Māori name, tuwhaipapa, derives from the Māori god of newly made canoes.
The snout is longer than the entire body, and there is a long antenna at the very tip. Females bore into rotting logs to lay eggs during October to March and the grubs remain there for up to two years, feeding on fungi and yeasts on the decaying wood. The hole the adult leaves as it emerges is not round, but perfectly square. The males, which can grow to nearly 10 cm, fight with their snouts when competing for territory. Adults can fly, but only live for two weeks.

[devil350]

Excellent shots, and nice found.

Thanks for all the nice compliments. :)
Now I may have to hide my head from lance v in case I trample on this weevil ;)
