Random amblypygi questions

[Purplepuffball]

1. Are all Charinus species parthogenic, like charinus israelensis and others...

2. How does the clutch size of different species compare (As fully matured specimens)? (specifically whitei, maesi, barbadensis, longipes, and marginemaculatus)

3. What is the growth rate of phrynus longipes, and how big does barbadensis get when full sized?

4. Which amblypygids species generally have the best feeding response?

5. I know whitei can only be paired of cork; with that being said, do they need to be kept of cork even after the initial pairing in order to produce a clutch? Because I want to rehouse a paired female on styrofoam, but am unsure if it will have any adverse effects.

6. If a gravid female is shipped, will it drop its sack?

7. How does maesi compare to whitei in size and behavior?

7. How does maesi compare to whitei in size and behavior?

1. I’m not sure if we have enough data on this, I believe I know of at least 3 Charinus species and one Sarax that have been scientifically recorded to do so.

2. There isn’t exactly a hard rule, but as a general rule clutch size seems to scale with the size of the female compared to max species size, and even moreso how well she is fed. Small species seem to produce fewer offspring, example Charinus can have as few as 4 offspring, and I’ve had a large Damon johnstonii have 64 offspring. Specifically for the species you’ve mentioned there can be tons of variation- I’ve had a maesi female produce ~45, and a marginimaculatus only ~17, but others have had huge marginimaculatus clutches as well.

3. This depends on which locality of longipes you have. My PR longipes are extremely fast and molt once every couple months, but my DR longipes took their time. My barbadensis adults are only a few inches legspan, maybe an inch and a half larger than marginimaculatus.

4. Acanthophrynus and Heterophrynus destroy food IME, but generally all my juvenile Phrynids are great eaters.

5. I’ve paired whitei on styrofoam no issue. No eggs yet but the spermatophore was made and taken just fine.

6. As long as the eggs aren’t too fresh I’ve had females shipped to me and the eggs hatch fine, but it’s definitely a stress risk.

7. Maesi are a lot bigger, like 5” legspan compared to the 3” or so you get with true whitei. Maesi are also very sexually dimorphic as adults.
