Bugs in Melbourne, Australia
January 12, 2010
I was wondering if you could please help me identify these bugs. We have had many, many of them flying around our home in the past few weeks, and many are dead on the window sills. I cannot work out where they are coming from and am worried they might be borers, however could they be some type of food weevil? (Some of the legs and antennas have fallen off these dead ones, when I moved them to photograph)
Your letter is the third we have posted in as many days from readers with infestations of tiny beetles found in the kitchen, and all three were different species. We believe your beetles are Drugstore Beetles, Stegobium paniceum, which according to BugGuide: “larvae feed on prescription drugs, flours, dry mixes, breads, cookies, spices, chocolates and other sweets, plus a variety of “non-food” items (see Remarks section below) adults do not feed. … Remarks … Larval non-food material includes wool, hair, leather, horn, and museum specimens. Larvae have been known to bore into books, wooden objects, and, in some cases, tin or aluminum foil and lead sheets.“
We hope one of our readers can confirm this identification.
