Podisus nymph, testing out a key - Podisus serieventris

Podisus nymph, testing out a key - Podisus serieventris
Columbia, Grindstone Park, Boone County, Missouri, USA
June 23, 2011
EDIT: I've removed my discussion about the nymphal Podisus key. I misinterpreted the key at the time and it seems to check out in this case.

At the time, I think the wording of the colors in the key confused me. The Evans key calls the dorsum of the abdomen white and mentions creamy-white patches for maculiventris. My thought was that white would refer more to what we see in the white from P. placidus here, so I think I got hung up thinking that the dorsum was creamy-white as opposed to white and needlessly eliminated serieventris. Poor interpretation on my part.

Update on this
Hey Anita, I think you are correct. I went through and reared another one out and went back through the key. I think the wording of the colors threw me off. I edited the description above to reflect what I messed up on.

Thanks for the followup
Glad you got it sorted.

P. serieventris or maculiventris?
Hi, Andrew. Text says it keys out as maculiventris, but it's filed under sereiventris. I (re)found what I imagine is the same key here: I'm not seeing the yellow-orange patches on the anterior abdomen that are supposed to be diagnostic of maculiventris.

I have 1 of my own I'm trying to ID, just posted here:


The key thought this nymph was P. mac, but upon rearing this individual to adulthood, it turned out to be P. serieventris. Meaning that key is probably not all that reliable.

If you've still got that individual you're trying to have ID'd, it would be a huge help if you could raise it to an adult. My e-mail is on my account page and I could walk you through rearing it fairly easily. Thanks!

Garden friend or foe?
I have come across a number of these in my garden in central nj. I have a pollinator garden around my house and veggie beds, bug boxes too... I'm wondering if these are killing my butterfly caterpillars and other bugs I've been trying to establish like lacewings and lady bugs.

Nope, just a random backyard bug
that I snapped a pic of. I'll keep my eye out for them in the future, though.

Are we looking at the same key? Because I don't have a lot of experience with these, but as I read it, maculiventris should have yellow or orange on the anterolateral abdomen (ie, partially hidden by the wingpads here), & yours looks pretty solidly the same off-white as the rest of the abdomen to me. Maybe there's some subtle color there & I'm just missing it, but maybe we're looking at 2 different keys -- they original link was broken, so I just googled it.

Whoops, I see what you're sayingThe folks I've talked to
The folks I've talked to have indicated that the key might be a bit outdated and not to rely on it. I ended up getting to work with this species for close to five years in college and noticed and noticed large amount of variability in the nymphs that kind of contradicts the key or at least renders it incomplete.

The patches do look a little bit lighter than the key calls for, but I didn't think they were white like serieventris. I see what you're saying though. Maybe it keys better than I thought. I'll have to see if I can't find some nymphs this summer to rear out to adulthood to tell for sure.
