Author Message   Malgorzata  Supporting Member My Garden Posted on Friday, September 07, 2007 - 01:41 am EST :    Do you happen to know the name of this bug? It has been making my gardening life miserable for decades and still I can not find out what bug is it. The scores of it come unexpectedly, usually after the rain and munch on Dianthus, Soapwort and now even on Impatiens. The only means of destroying seems squashing! Yuck! It is immune to anything else I have tried. In size it is may be slightly bigger (or not) than the ladybug. Any ideas?

Aulacophora nigripennis http://www.pmnh.org/en/insects/f_co_hamushi.html http://sciencelinks.jp/j-east/article/200205/000020020502A0103945.php Bluethumb - Alberta, Zone "3b"   Malgorzata  Supporting Member My Garden Posted on Sunday, November 18, 2007 - 05:36 am EST :    Oh my, Alison! You've got it!! Thank you! Malgorzata - Fukuoka-Kyushu, Zone "8/9"   Growit  My Favorite Photo My Weather My Time Posted on Monday, November 19, 2007 - 04:44 pm EST :    Great site Alison. I just came on here to see if anyone had identified Malgorzatas' bug and the link you have given shows lots of different insects, not just beetles. I hate not being able to identify an insect in my garden. I have saved it to my favourites for future reference. Thankyou for posting it.

I thought Malgorzata's bug reminded me of the weevils I discovered this year chomping my plants to bits, so started looking for that and tripped over the site. Hit the jackpot in 'beetles' and loved the fact there are real photos which help so much in identification. A picture really is worth a thousand words.

Will you try it Malgorzata? Gardenfiend - Germany, Zone "7a"   Malgorzata  Supporting Member My Garden Posted on Wednesday, November 21, 2007 - 07:04 am EST :    The "trap plant" strategy sounds very good! Will you try it ? Mara, that is the main problem that I want to grow "the trap plant" (Dianthus) as a garden plant and I can't! Malgorzata - Fukuoka-Kyushu, Zone "8/9"   Gardenfiend  Supporting Member My Weather My Garden Posted on Wednesday, November 21, 2007 - 09:19 am EST :    As I understood the abstract, the trap plant was a specific Dianthus: D. pungens (which I've never heard of). Apparently the bug prefers it to other Dianthus, so maybe if you plant a couple of the pungent ones, they'll chomp it and leave your others alone. Unfortunately (?) it looks as though D. pungens is attractive in its own right (click this), so it probably wouldn't be fun watching it being destroyed either. Gardenfiend - Germany, Zone "7a"   Malgorzata  Supporting Member My Garden Posted on Wednesday, November 21, 2007 - 08:03 pm EST :    Hi Mara! That name Dianthus "pungens" is very confusing to me. I did seem to grow a very similar Dianthus last year. Heavenly fragrance when the plant lasted. I guess the plants had to be regularly replaced. When one Aulacophora nigripennis finds the plant, on next day there are three critters, by the end of the week it is covered all over in the black spots. Something like one ant bringing the rest of her coworkers? :( By the second week the plant is munched down and the herd moves to the next plant No.2 on their menu list. Disposing of the first visitor and the next three was never successful in keeping the herd away from the plant once noticed by the first critter. They have some kind of radio communication! Nature is fascinating! But these critters are frustrating! Malgorzata - Fukuoka-Kyushu, Zone "8/9"   Pinkdamsel  My Weather Posted on Thursday, November 22, 2007 - 03:37 pm EST :    Wow Mal! What a terrific pic! Glad Bluethumb identified it. I absolutely love to photo (macro) insects in my garden. I'm not always happy in what I find though.
