This bug is eating my cucumbers, beans, and radishes. It’s killing the leaves. I’ve been finding them on the leaves that are shriveling up with holes in them. What should I do?

Striped Cucumber Beetles

Dear Kim,
You have an infestation of Striped Cucumber Beetles, Acalymma vittata.  According to BugGuide:  “The most important hosts, perhaps the only larval hosts, are Cucurbitaceae” so it is possible something else is eating the beans and radishes.  The University of Connecticut Integrated Pest Management website has helpful information on the control of the Striped Cucumber Beetle.

This little beetle is covering many trees in our small town of Johnstown Colorado and stressing the trees severely. I’d like to know what it is and if there are any safe means of getting rid of it. If there are no safe means what would be the least toxic method ?
Thank you,
Terry

Elm Leaf Beetle

Elm Leaf Beetle

Hi Terry,
Your photo is very blurry, but we are relatively certain this is an invasive, exotic species, the Elm Leaf Beetle,
Xanthogaleruca luteola.  The University of California Agriculture & Natural Resources Statewide Integrated Pest Management Program has some helpful and comprehensive information.

Bright red beetle walking around in the splash from a fountain on the patio?
Is it going to eat something I’m trying to grow?

Reddish Potato Beetle

Reddish Potato Beetle

Dear gnatknees,
It did not take us long to identify your Leaf Beetle as a Reddish Potato Beetle,
Leptinotarsa rubiginosa.  BugGuide reports the Reddish Potato Beetle from Arizona and New Mexico and states it feeds on Solanacea, the family that includes tomatoes, peppers and eggplant as well as potatoes and many native plants like jimsonweed and nightshade.  We are not certain if they indiscriminately feed on all members of the family, or only certain plants, but the family contains many cultivated food plants as well as some ornamental garden plants.  We believe this is the only example of this species in our archives, so thank you very much for submitting your excellent photograph.

Unknown Longicorn

Longicorn:  Cerambyx scopolii

Hi Sue,
Beetle #1 is a Scarab in the family Scarabidae, but we do not know the species.  Beetle #3 is a Longicorn in the family Cerambycidae, but we do not know the species.  Beetle #2 is striking in color and markings, but we cannot determine its family.  It somewhat resembles the Pleasing Fungus Beetles in the family Erotylidae, but your photo does not reveal enough of the physical characteristics to be certain.

I found this cute little guy on the side of my coffee mug. He looked like a drop of gold! I snapped a few photos, and when I scrolled in for a closer look I realized that the edges of his exoskeleton are actually translucent! Very beautiful insect!

A horde of these critters attacked my lilies, which I just discovered this morning (June 26). All the leaves were gnawed off, all the buds chewed into. I found zillions of these guys on the stems and buds. Of course they just fly off if I try to get them as I’m removing the dead plants. But they just moved next door to my stella doras, staging on the mum plants between the destroyed lilies and the stella doras.
I can’t find this in any of my bug books. Can you tell what it is? Is there anything much I could do about it? Obviously they love the lily family, but would they likely move on to other plants if these were not available?

Lily Leaf Beetle

Lily Leaf Beetle

Dear Sister CG,
This is a Lily Leaf Beetle, Lilioceris lilii, and it is an introduced species that has not made friends with gardeners who cultivate lilies.  You can read more about Lily Leaf Beetles on Gardener’s Supply Company.

Ah-HA! Thank you so much for this quick reply. I’m off to research possible treatments for this. We have a fully organic farm here, and the affected lilies are already goners for this year, so I’m thinking vinegar/water/soap to begin with. We’ll see.
Again, thanks so much for the help! (And no, this gardener is not in the mood to make friends with these guys either, pretty as they are.)

We hope you are able to find an eco-friendly means of eradicating this invasive, exotic species from your farm.
