  1. My best advice: keep the elytra closed and change the substrate monthly.
  2. Goliathus orientalis orientalis?
  3. Given the elytral ridges, I'll then stick with my guess that they are S. paniceum. And yes, they should have no problem living on old rice - along with many more unlikely items like straw, leather, wool, strychnine, and opium.
  4. If there are ridges running down the back, I'll guess it's an insect closely related to the cigarette beetle: Stegobium paniceum, commonly referred to as the drugstore beetle. As this ordinary name implies, they can survive on a remarkably wide variety of foods, including stuff that wouldn't be consumed by other insects or might actually be toxic. Although they can't harm people directly, they are, like many Ptinids, quite resilient, found worldwide, and thus classed as pests. I wouldn't worry about their presence unless you are finding them in really large numbers. If you are interested in insects, they might even be fun to culture so as to observe their full lifecycle and style of living. Please keep in mind that I'm still only making an educated guess here. There are seasoned taxonomists on this forum who could definitively key out the beetle if at least one extremely clear, detailed close-up was available. Hope this helps a bit anyway...
  5. Possibly Genus Ernobius? I don't know your location, nor can I make out the antennae: both can be important for definitive ID. Many species of these Ptinids are reported to be associated with conifers, but it's best for the real experts to weigh in here...
  6. by Stephen A. Marshall, Firefly Books Ltd., 2018. By any standard this is a big book. It is 2 inches thick, weighs 7.5 lbs., and sports 784 glossy heavyweight pages, most lavishly adorned with color photos. Marshall is professor of entomology in Canada and has authoted at least two other large volumes. Here, he undertakes an ambitious taxonomic review of the Order, supported by various pertinent field observations and illuminating facets of natural histories. There is a dichotomous key to principal Families at the end and an excellent index. However, this book is primarily geared for academic interest; no space at all is devoted to captive husbandry, despite the fact that keepers and breeders of live beetles are responsible for the lion's share of popular interest in the Order. In any case, this is a beautifully produced volume and reflects a real labor of love. It would be a wonderful addition to any entomophile's bookshelf or coffee table.
  7. by Thomas Blanchard. Apropos of spring, whatever you make of the message:
  8. I too am appalled by this grotesque breach of taxonomic authority! There oughta be a law...
  9. Translation please! Inquiring minds -- and my pet beetles -- want to know! 😉
  10. Congratulations on this; the updates are fascinating and very informative. Best wishes for the whole amazing family!
  11. Thanks! To the taxonomically naive - like me - it seemed the two genera would be more closely linked than mere occupants of the same superfamily. However, your note that larval similarity must always take a taxonomic back seat to adult form is very appropriate.
  12. To a layman, there are remarkable morphological and lifestyle similarities between Platerodrilus and Lamprigera. Yet the latter are Lampyrids! What is the phylogenetic relationship between these taxa?
