  1. If you have an opportunity to visit a freshly-burned forest, look for pyrophilic beetles (e.g., certain species in Sericoda, Melanophila, Monochamus) and flies (Microsania). Some have specialized antennae for detecting smoke, others use infrared-sensing areas on abdomen or thorax to locate hot spots. #fire #smoke #weather #canada #beetles #coleoptera #insects #flies #trees #forests

  5. #WeevilWednesday: some people have been confused about how female hollyhock weevils (_Rhopalapion longirostre_) use their long snouts, so here you go. Her mouthparts are at the end of the snout. She chews a tunnel down into the heart of the flowerbud. Then she turns around, extends her ovipositor (at the end of her abdomen), and lays eggs down the hole. The larvae have a safe place to grow, with plenty of food!

  9. An oddly shaped True Weevil (family Curculionidae) spotted at Rifle Range Nature Park, Singapore on 29 June 2025. Such huge eyes, on a stout body.

  10. Beetles from the other day:

    - Red milkweed beetle (_Tetraopes tetrophthalmus_)—the scientific name translates as "four-eyes four-eyes", note how the antenna divides the eye in two; on its host plant, common milkweed (_Asclepias syriaca_)
    - _Valgus hemipterus_ on Queen Anne's Lace (_Daucus carota_)
    - Grapevine beetle (_Pelidnota punctata_) on Virginia creeper (_Parthenocissus quinquefolia_)
    - Hairy flower scarab (_Trichiotinus_ sp.) on some kind of spiraea

    All scarabs (family Scarabaeidae) except for the milkweed beetle who is a longhorn beetle (family Cerambycidae).

  11. Middle-aged lady, seeing me hunched over peering into the Queen Anne's Lace (_Daucus carota_) in a garden bed at the park: "Did you find it?"

    Me, in an "oh my god, it's full of stars" tone: "I found them *ALL*!"

    Lady, looking at the flowers: "They're beautiful, aren't they."

    Me: "I'm not sure we're talking about the same thing but YES."

  12. #WeevilWednesday: I suspect this little fellow I found under a dead leaf in the strawberry patch is a strawberry root weevil (_Otiorhynchus ovatus_). Very sus. :thonking:

  16. Good morning, it's #WeevilWednesday! Tragically and inexplicably, the patch of hollyhocks in the park near me is devoid of hollyhock weevils (_Rhopalapion longirostre_) so far this year. God knows it's not because anyone takes care of that bit of park. Luckily I know of a few other gardens in the neighbourhood with weevil-ridden hollyhocks right by the sidewalk.

    Here you can see the difference in length between the typical male and female snouts. The females' long snouts help them bore deep into the flower buds to lay eggs.

  20. Last night went out for a good bug ramble except I realized I forgot my light, so I went home and made do with my phone flash along the way. (OpenCamera has a torch flash mode where the flash is always on.)

    - _Leptinotarsa_ potato beetles mating
    - a huge _Clubiona_ leaf-curling sac spider eating a zebra jumping spider (_Salticus scenicus_)
    - an ant war (_Tetramorium_?), this was only one of two large patches, with skirmishes up and down the sidewalk
    - a *huge* sawfly larva? of some kind

  24. It is Weevil Wednesday, and my Weekend starts early.
    Not much is happening at work, so when I started running orders for Monday, I texted my boss to ask if I shouldn't just go home and stay there for a few days. Fortunately, he agreed.

  28. More #WeevilWednesday because I can't resist: it's also a superb time to find the stunning green immigrant leaf weevils (_Polydrusus formosus_) on young willow shoots.

  29. Folks, this #WeevilWednesday I am thrilled to announce that the hollyhock weevils (_Rhopalapion longirostre_) are back!! The females are the ones with the extremely long snouts, for drilling into hollyhock buds.

  30. #WeevilWednesday: The other day I was at a native plant gardening thing and afterwards a few of us were checking out an overgrown patch and noting various plants. There was a lot of Canada thistle, _Cirsium arvense_ (which isn't actually from Canada) and I said the only good thing about it was that it often had weevils. And right then I spotted a Canada thistle bud weevil (_Larinus carlinae_) on one of them! I made the others look at it because LOOK AT IT.

    Then I had to ask one of them to hold it for a moment so I could grab my clip-on macro lens and put it on my phone for photos.

  31. You know what day it is. It's #WeevilWednesday. Post 'em if you got 'em.

    I think this is _Barypeithes pellucidus_, a. k. a. the hairy spider weevil. Found in the garden snacking on a dandelion stem with its snoot covered in pollen.

  32. Egg of a redbud seed weevil (Gibbobruchus mimus) glued to the edge of a seedpod. I've been taking photographs just in case it's possible to see when they are parasitized by fairy wasps (Mymaridae). Likely futile. #bruchidae #beetle #insect #coleoptera #nature #macro #redbud #wasps #macrophotography

  33. It's the first #WeevilWednesday this year that I've actually been able to go out and find a weevil! Take a closer look at this snoot!
