Talk about a life list critter, I've finally found a male cottony cushion scale insect (pic 1)!!
Male scale insects are rare in general but this species is composed almost entirely of simultaneous hermaphrodites (pic 2)! Rare pure males can occur, but we don't fully know under what conditions.

Such a fun and productive trip! Be on the lookout for more on evolutionary genomics and systematics of bagworms from my lab and @dr-akito.bsky.social 's lab soon!

Getting ready for #Evol2025. If you see me say hi!
I'll be doing a very preliminary talk on bagworm moth evolutionary genetics on Sunday at 11:45 as well!

Well if that's the game of the game...here's a shot of Fulgora lanternaria from a recent trip to Costa Rica.

How do you differentiate species when the most visible lifestage is a featureless brown rugby ball?
You sequence it and place it with phylogenomics!
Read all about this and the evolutionary genetics of a moth-infecting apicomplexan #parasite in our pre-print here:

Some more mantidfly mania for #WorldBiodiversityDay
These two were photographed in Costa Rica, where my lab is currently doing fieldwork (more on that soon)!

You can divide a hot minute by 60 and it has the same value, baffling

This is far from the most salient problem with the new "dire wolves," but while we're all dogpiling this story...they couldn't even name the female pup Arya or Sansa? They went with the title (not even name) of the war crimes dragon lady...absolute hacks

Excited to announce another genome preprint! This one is first-authored by my first master's student, Tracy!
We generated a chromosome level genome for the invasive hibiscus mealybug, a citrus crop pest.

Okay wrapping up: this odd genetic system creates contrasting evolutionary dynamics for the sexes. How do these patterns extend to longer evolutionary time? More soon, stay tuned to the Mongue lab as we continue exploring paternal genome elimination and other weird repro!

If we look at the amount of adaption involved (let's save the pop gen methods for a future thread?), the pattern reverses: female-biased genes evolve less adaptively than those expressed in males! Why? Because haploid selection slows evolution but also removes more weakly deletetious variants.

So different dynamics for the sexes and lots of sex-specific gene expression? This creates differing evolutionary trajectories for genes. First, genes expressed partly or entirely in males more slowly than female-biased genes. Evolution is faster on the female side in mealybugs! But..

As you've maybe noticed, males and females are highly sexually dimorphic! Males are small, winged, and don't eat as adults. Females are large, sessile, and long-lived. This dimorphism extends to gene expression as well. Most genes are expressed in one sex or the other, but not both.

This dynamic has two consequences: (1) males express genes in a haploid state, which should create more efficient selection than in diploids (2) fathers cannot pass on genes directly to their sons. They have to pass through a daughter to end up in a grandson.

Mealybugs are sexually reproducing but have no sex chromosomes. Sex is determined by whether an embryo expreses 1 or 2 copies of the genome, so haplodiploidy BUT unlike other haplodiploids, eggs that develop male are fertilized too. They just eliminate their paternally inherited chromosomes!

Wow, lots of new followers this week! To celebrate and (re)introduce myself, I want to share one of the weird reproductive systems my lab works on: Paternal Genome Elimination in mealybugs. If you have house plants, maybe you know these waxy little pests already. But do you know their genetics?

When you watch Jurassic Park but have a background in reproductive genomics...
"All vertebrate embryos are inherently female" assumes XX/XY sex chromosomes, but all living dinosaurs (birds) have ZZ/ZW chromosomes which would be "inherently male" from this perspective.

How do sex-biased genes evolve in a highly dimorphic bug with weird reproduction?
Female-biased genes evolve quickly but less adaptively; male-biased genes evolve more slowly but with more positive selection in mealybugs.
