  1. Sawfly larva charm point #3: The thing they do where they curl up into little spirals. #insects #bugphoto #bugstodon #sawflies

  2. Sawfly larva charm point #1: Their round heads and beady little eyes, which make them look like an adorable cartoon rendition of a caterpillar. #insects #bugphoto #bugstodon #sawflies

  3. Here is a great video to start your day from tumblr:

    (A video showing various hymenopterans: bees, wasps, ants, collecting pollen, eating and climbing on plants cheerful inspirational text matches the lyrics of the classic song from The Killers "All These Things That I've Done" At the end of the video text flashes that says "i forgot sawflies" ... EVERYONE forgets the #sawflies)

  4. A female cattle-poisoning sawfly, Lophyrotoma interrupta, lifts off. Presumably to poison some cattle? Who knows. (Australia).

  5. This is an invasive from Asia, sadly. Especially unfortunate as elm is already having a disastrous time.

    No surprise at all to learn that it is called ZigZag!

  6. I hope these two purslane sawflies weren't looking for privacy. #Insects #Sawflies

  7. I think this a bristly rose sawfly (Cladius pectinicornis), a gregarious defoliator introduced from Europe. Can also be reared on strawberry so I might try maturing some to adulthood on potted, netted plants. Males have bizarre, pectinate (comb-like) antennae. #sawflies #roses #hymenoptera #insects #rosa #pests

  8. Turns out I had seen the sawfly Macrophya annulata once before, in 2022, and had confused me – it's an effective spider wasp mimic.

  9. Another unusual insect: Tenthredo baetica (ssp. dominiquei), with only 118 observations world wide, of which 29 for this particular subspecies. It's a wasp – sort of: a sawfly.

    The rear limbs are rather large, and I wonder why. For carrying prey?

    Wikipedia points out an interesting reversal: in the Tenthredo genus, the larvae eat plants while the adults prey on other insects. Whereas many typical wasps do the opposite: the adults sip nectar but hunt insects to feed their young. en.wikipedia.org/wiki/Tenthred One wonders then what is this adult doing on a flower, engaging in motion patterns characteristic of foraging on nectar and pollen.

  11. Seeing a lot of these little guys flying around Austin. Halidamia affinis, a small sawfly that feeds on Gallium catchweeds.

  12. New on Entomology Today: Conifer sawflies are common throughout North America. Typically little more than a nuisance to individual trees, large outbreaks are capable of defoliating thousands of forested acres in a very short time. A new review in the Journal of #IPM summarizes what we know about conifer sawflies, provides an identification key for larvae, and outlines management options for both managed and natural landscapes. #entomology #insects #sawflies entomologytoday.org/2023/08/15

  13. Wildlife gardening has been very rewarding for me but it's not all shiny successes. When I first moved here the garden had been drenched in weedkiller and very little grew until the third summer. One of the first plants to recover was meadow cranesbill, aka Pig yr Aran y Weirgoldd (Geranium pratense), which is loved by pollinators but also by hungry sawfly larvae. For two years it flowered before it was eaten to skeletons by the sawfly larvae, which were then eaten in their turn by birds and predatory minibeasts. But in year three the cranesbill died back significantly and there were no flowers, partly because of the weather and partly because, following the wild plants, the plant-eater population recovers faster than the predator population. Finding a balance takes time and patience (and is ideal therapy for perfectionist tendencies, lol). Appreciating the beauty of leaves eaten into pretty lace requires adaptability, but it's worth doing.

  14. Nematodes, from a pest insect that they had been breeding inside. While gory, #nematodes are a #biocontrol option for various invertebrate pests. Various species are available commercially, and can be effective against a range of species. They can be particularly good against insect pests with a soil-living life stage, such as #VineWeevil (and other weevils!), some #Sawflies, root maggots and other #Diptera larvae, etc. #LoadsaTodes

  15. An interesting iNaturalist observation of the week.

    "Our Observation of the Week is this group of sawfly larvae (potentially in the genus Caliroa), seen in Germany by @ingrid\_kulozik!"
