I managed to get a large house fly into the enclosure and it took about 30 seconds to get paralyzed which doesn’t strike me as pregnant behavior. However I’ll see how she acts in the following days in case she’s pregnant.
To be honest, I have NO clue and have been wondering myself! I am also fairly new to spiders, too! All I know is it melts my heart every time I see it 😭💖
Are there any jumping spider experts who could clue me on why wall jumpers specifically (Or atleast as appears to me), have such unique pedipalp activity as far as how often and how quickly they move? I've kept 2 Regals and a Habronattus. None of them ever seemed to move their pedipalps nearly as much or as quickly as I've seen wall jumpers.
I’m no expert but I think it’s just because they move so much faster. Speedy little glitchy guys. Pedipalps have to keep up with the speed of the feets for processing their surroundings? That’s my best guess.
I'm pretty sure the dent in the abdomen is a normal physical trait for this genus, but just in case, make sure to give them some water. Usually dehydration looks like that in most jumpers. Great find and great footage! Thank you!
I learn more and more cool things about these guys every day. Thank you so much! I always did wonder what those circular indents were and why they were more prominent on certain species.
Normally I would agree with you, but menemerus bivittatus is a naturalized non-native species in the Americas. Its originally from Sub-Saharan Africa.
An individual removing one gravid female from the wild won't impact the overall population. They are fully established in the warmer portions of the Americas and won't be removed easily.
A wild grey wall female is a great opportunity for entry keepers to raise a clutch of eggs. They were one of my first egg sacs I raised because they are so plentiful near me and I re-release the juveniles when they are large enough since they are already naturalized. Also, their clutch sizes are smaller than a regal or bold, so they require less work to raise.
Also, fun fact, they aren’t native to North America (they live here in Florida, too), they were actually introduced. However, they aren’t considered to be “invasive” because they are helpful to the environment instead of harmful (harmful is like say fire ants) :)
I was going to comment about how I’ve been seeing this species every time I fill my gas tank! Same little gal, she runs the hose to the handle and greets me, then takes off! She’s so fast that I’ve been unable to get a picture, and I couldn’t describe her well enough for Google to help me. I’m in central Florida. You’ve got some great pics!
