Black Beetle with 4 Yellow Spots on Lucifer Bulb.

eigdeh(z6 NJ)April 15, 2010


Planted Crocosmia 'Lucifer' last year and only half are shooting up greenery. Probably not unlikely that the others will still shoot up stems soon, but I got curious and dug down to the side of a plant that is still all brown. Bulb looks good except for one spot where I saw two black beetles about 3/8 of an inch long and they both had 4 small yellow spots on their back. Where they were on the bulb there is a soft spot perhaps half inch wide and 1/4 inch deep. Should I be concerned? Are there beetles that attack bulbs? Wonder if the soft spot came first or the beetles.

Anything I should do? Are they going to attack all my bulbs? I have tulips, daphodils, Iris, and lillies in the same bed.

A good website for bug ID is BugGuide. If you scroll down you can see all the different photos of beetles. If you have a photo of your own you can go to What's That Bug? and post a query.

Thanks Linrose!

I went to the bugguide and it looks like this:

So I am pretty sure it is a Sap beetle (Glischrochilus fasciatus).

I am guessing that there is sap in the Lucifer bulb and that the bulbs might be in trouble. :c(

Anything one can do for this?
