Molt dates

OK, so I have 11 spiders at the moment ranging from spiderlings to adult. I have noticed that they all seemed to come into molt at the end of last year which is normally a bit unusual for he UK. May have been the mild winter who knows, but just thought I would share the molt pattern with you all. Naturally, I have plotted them on a "WEB" chart....lol
Pet name and molt date used on the chart. I chose August as this is when I started to increase my collection with autumn/winter proving particularly busy buying periods...lol. I have 5 other waiting to be plotted but I think 2 are in pre-molt. Obviously, there are variables in here such as growth rate, the fact some are spiderlings rather then mature etc but just thought I would share.

Does anyone else have a particular busy period for molt activity?

I kept a log of the number of moults each month last year for that very reason and have started one for this year to compare.

Do you have it with % against it too. So for example April is 55% of all Ts, Dec is 39%. Nice table. Must admit I love a good spreadsheet.....lol

My GBBs, P .irminia, C. darlingi and A. ezendami (I have several sacmates of each species) tend to all molt within a month or two of each other (by that I mean the GBBs molt together, but not necessarily at the same time as the ezendami), which is to be expected. They're never on the same "schedule" as my juvenile Bumba cabocla, Euthlus parvula, P. fasciata, and L. parahybana, or sub-adult and adult Brachypelmas and Aphonopelmas, which is also to be expected given the different growth rates of each genus and age of the spider.

Providing that all the tarantulas are fed on the same schedule, and kept at the same temps, you should see molts come in groupings sometimes. Once you have a lot more though, a chart is likely to look more like buckshot from target practice lol

@Phil I hadn't worked out percentages but it's fairly easy to see roughly
Yeah its dead easy....those are the %for April and December in my reply and then just copy the formula down. Did you do the table in excel? If you did the formula can be repeated for when you add to your collection as I am sure you will looking at the trend on the number of Ts you have....lol

Ha ha....you are right it probably will. Just thought that particular chart style "hit the target" (pardon the pun) as it looked like a web....lol

so far i only have 1 T that has molted more than once. 2 others just started premolt so i'll have a bit more data to work with. and 2 of the ones that haven't molted yet are starting (or maybe molted already as i haven't seen them for weeks, my son picked the perfect name for his B. albo - Missingno ;))

I have a spreadsheet with Marley's molts for my son's project ( i stole it from his school google docs) and i'm not sure the sizes are quite accurate, so we'll be measuring his molts tonight. Glad he had the idea to keep all of the molts :)

Here's a screen clip of the info for Marley that he has, we'll update after we measure this evening.

For multiple Ts, it may help also to separate them as slings, juvies, sub-adults and adults since slings obviously molts more than adults.

Just my 2cents on the matter. :p

finally got around to measuring all of the GBB's molts. Kind of interesting seeing how she's grown each molt.
Code:
	Size recorded in inches	
Molt date	         size of molt	      growth
June 13, 2015	              0.75	       0.50
July 19, 2015	              1.25	       0.25
August 30, 2015	              1.50	       0.25
December 28, 2015             1.75

My son was able to measure her while she was somewhat spread out climbing on the side of the enclosure. She's almost 2.5" now so that'd be her largest growth yet. We'll find out for sure when she molts and can measure that :)

Interesting. I've never really cared to record molts, mostly because I'm able to remember them pretty easily. I write it down sometimes, but that's it. Maybe I'm the minority, but I don't keep the exuvium either.

In your signature, Marley's last molt is Dec 20 while in the table quoted above it's Dec. 28. Just pointing it out, no biggies. :)

When I had only 4 T's, my Juve GBB and my P. metallica sling moulted on the same day which I thought was a coincidence, but maybe there's more to it.

Then about 2 weeks later my 2 P. murinus slings moulted on the same day. But they are siblings so that's probably to be expected when they're tiny.

I use the Tarantulas app on my smartphone to keep track of all my moults, feeds, rehouses etc. I find it very useful. I can see at a glance when the last fed and last moult dates were.
