It’s tachinid fly in S. California see my posts on this. I started dissecting. Even the so called, “Black Death” is tachinid fly. Monarch watch’s scientist Dr. Chip backed me up in my observations, said we need studies. Instead, everyone’s been sidetracked by unfounded milkweed hypothesis.

Different topic but I raised some 30,000 monarchs with Red Bull and Snapchat monarch gardens… I started collecting data and realized tachinid flies were parasitizing 80% of our monarchs.
Dr. Chip of Monarch Watch agreed with my observation for S. California on this, said that we need studies.

In S. California 80% are wiped out by tachinid flies who parasitize. The “OE” so many worry about is still 10% or less, and NOT a concern. Praying mantis will descale butterfly populations, so we relocate them to non butterfly gardens. Climate warming is the biggest threat to all pollinators, and us

🪰Winthemia "pinguis"? parasitic tachinid fly targeting Lepidoptera larvae. Native to North America, adults feature hairy eyes, short proboscis for honeydew feeding, and oval abdomens. If I have correctly identified the species, this is an invasive species in Brazil.

Spiny Tachinid Fly

The photograph shows a large, robust fly perched on the center of a bright yellow, daisy-like wildflower. The fly’s body is thick and barrel-shaped, colored a warm golden-orange with bold black markings. Coarse, stiff black bristles, almost spine-like, cover much of its abdomen and thorax, giving it a prickly, armored appearance. Two clear wings extend diagonally back from the body; they are lightly tinted amber by the reflected yellow of the petals beneath them. The fly’s head is dark and rounded, with large, bulging eyes and short antennae. The flower’s petals radiate outward like narrow sunbeams, filling most of the background with saturated yellow, while the surrounding meadow is softly blurred into greens and tans, suggesting shallow depth of field and bright mountain sunlight. Tachinid flies are among the most important natural biological control agents in terrestrial ecosystems. Although the adults often visit flowers for nectar; making them incidental pollinators. Females lay eggs on or near other insects, typically caterpillars or beetle larvae. Once hatched, the tachinid larva develops inside its host, eventually killing it. This life strategy plays a significant role in regulating herbivorous insect populations, helping maintain ecological balance in forests and meadows. The dense bristles seen in this species are characteristic of many tachinids and may help deter predators or assist in anchoring eggs to hosts. The bright yellow flower is acting as a nectar station, providing energy for the adult fly in the high-elevation Abajo Mountains. Mid-August is peak season for both alpine wildflowers and adult tachinid activity, when warm days and abundant blooms briefly overlap before autumn conditions return to the San Juan County highlands.

You muscid in quick as they’ll fly off the shelves. Don’t tachinid my word for it.

a spectacularly successful native! (for me anyway, not sure where you are)
It is, at least, extremely popular with the little wasps and tachinid flies and those sorts of folks

Not a tachinid! I'm a dummy! It's a goddamn muscid, Mesembrina sp. I was fooled by its ridiculously large calypters and tachinid style face and somehow didn't look at the postscutellum in all my fussing. Thanks @khong-a-tach.bsky.social

The journal @ento-ea.bsky.social has a Call for Papers on the topic of Dipterans for Biological Control and Pollination.

Submission deadline: Saturday, 28 February 2026

Call for Papers Dipterans for Biological Control and Pollination Submission deadline: Saturday, 28 February 2026 Many flies (order Diptera) are beneficial to humans and provide valuable ecosystem services. In particular, various dipterans act as biological control agents of pest insects and/or as pollinators of crops, and their role in ecosystems is increasingly recognized. Traditionally, the focus of biological control and pollination has been on a restricted number of species, mainly hymenopterans, such as parasitic wasps and bumblebees. However, there exists an enormous natural diversity of insect species, in particular dipterans, that may be used for such services as well. The main entomophagous flies that prey on or parasitize agricultural pests are hoverflies (Syrphidae) and tachinid flies (Tachinidae). Other examples of predatory or parasitoid groups are robber flies (Asilidae), phorid flies (Phoridae), bee flies (Bombyliidae), flesh flies (Sarcophagidae) and elephant mosquitoes (Culicidae). In addition to hoverflies, the main dipterans that pollinate plants are bee flies, flesh flies and blow flies (Sarcophagidae and Calliphoridae), midges (Ceratopogonidae), tangle-veined flies (Nemestrinidae) and tachinid flies. Few efforts are being directed towards developing these alternative species for exploitation and application in pest control and crop pollination. With this Special Issue, we aim to contribute to filling the knowledge gaps about the biology, production, exploitation and application of dipterans that are useful for biological control and pollination, often playing both ecosystem services. We aim to cover both fundamental studies on the biology and ecosystem role of these flies as well as applied research into their rearing and application. We welcome mini-reviews and original research articles that advance our understanding of dipterans in biological control and pollination.

stumped by this tachinid. supposedly collected in Oregon but doesn't resemble any nearctic genus that I can suss out. hard to confidently key out in the MND because most of the important parts are encrusted with mites. seems like it should be in the Dexiini tribe based on the antennae

🙏 I’ll ask for LA Fire community in recovery support donations! 🌱 Dr. Chip is good people - friend of my mentor of 16 years (Randy Oliver). Dr. Chip confirmed my observation that a whopping 80%!! Of S. California monarchs are parasitized by tachinid fly… tropical milkweed is NOT the enemy!

Nice shot. Looks like Popillia japonica, Japanese beetle. Introduced to North America (and Europe, more recently) and considered a pest, such as of roses. Keep an eye out for small white eggs laid on its pronotum - that's a tachinid fly parasite introduced to control the beetle!

One of the worst parts of winter is not having a lot of daylight, this means I sometimes have to do my nature watching in my office. Last week I found this Western conifer seed bug with Tachinid fly eggs (likely from the genus Phasiinae). #insects 🌿🪰
