| My lance leaf coreopsis is infested with a hard backed beatle. They have length wise stripes of orange and black, their bodies longer than wide. They do not fly. They are not attacking anything else including other types of coreopsis. I have been picking them off. I've never seen this beetle before, anyone know what it is? |

| Any chance of a photo? Nothing I've seen is coming to mind that would arrive as a group - several in the same plant. Are they doing damage, or just there? |

| Camara not working, maybe I can use my daughter's. Dozens in the same plant x multiple plants around a big yard. They are eating the plants. |

| I found something called coreopsis beetle using google, but it is more yellow and black striped with red near the head. Take a look and see if that is it : Calligrapha californica and Acalymma vittatum are two that are mentioned and there is another one that looks sort of like a ladybug. Not sure what you can do except choose something to spray them with. |

| ramazz, nice tip. I find mention of them in OSU ipm garden management, but haven't seen them and I have lots of thread leaf coreopsis, many years planted. |

| It is such a "buggy" year!!!! I don't have a clue about the beetle but I wanted to empathize as I have more eaten up seedlings than ever before. Sunday I planted out good sized seedlings of a perennial lobelia (a dark purple one I found last year among my Lob. sip light blue ones and saved the seed) and today they are in tatters - don't think they are going to make it. Even working in the garden is harder with all the flying bugs. I use to get bothered as it got closer to sundown and they started hyping up, but there are so many I feel like I am being nibbeled at all day long.Drives me nuts. I guess I am going to have to start putting spray on myself. I hope the beetle leaves you some flowers..... |

| I wonder if it may be the same beetles that infested my Pot Marigolds (Calendula) last year? If I remember correctly they were called Blister Beetles. They never caused no harm, and were mostly seen on or very near the bright yellow and orange flowers. I never did see them on my Coreopsis lanceolata though....just on the Calendula....hmmm I know yours are stripped and mine were solid black, but these beetles are more than one species. |
