Life Cycle postings

I would love to see more Life Cycle series posted like this:

If every member raised just one bug this summer.....

BTW, the contributor of this photo mentioned a link to a great Life Cycle site at:

Great series

Harmonia axyridis - daily from egg to adult
The insect hatched from the circled egg in this picture; adult eclosed on Day 18. There is at least one photo of each day as a larva, plus the first and last day as a pupa and the moment of eclose.

H. axyridis is very common and there are many photos on the Guide, but I figured a daily record of larval development could be valuable. For one thing, I found it identifiable within 24 hours of egg hatch, very useful for early recognition of this introduced and sometimes unwelcome species!

Labidomera clivicollis (Swamp Milkweed Leaf Beetle)

Life Cycle web site
I'm the person who started the Life Cycle web site -
I'm really interested in getting more people to raise insects, and linking to more life cycle series. I started the site - with the help of MJ Hatfield - about 6 months ago because the information about insect life cycles seemed scattered in so many different places. We'd like to be a central place with links to as many life cycles as we can.
If you have life cycles you could share, or would let us link to, please let me know. We'd love to have more contributors!

Life cycles
This is a very important subject; that is why I mentioned adultocentrism recently. I just added one life cycle of a fly; I was surprised at how little effort it took after all. Last year I placed another fly life cycle.
I have a whole bunch of goldenrod galls. I am waiting for the adults to emerge; if I am lucky I will get them all: the gall making fly, the two parasitic wasps and the parasitic beetle. I will try to get larvae and pupae at some point too.
I also have a moth pupa waiting.
I followed your suggestion and added the words "Life cycle" to help with the search.

One in process

Hasn't emerged yet.

I've had mixed results doing this. Except for the black swallowtails (with a 95% success rate) I've had about a 50% success rate with these 'life cycle' shots. This summer I tried a syrphid fly with no success....and I'm hoping that the moths make it.

Care needed
Don't forget that simple things like touching some pupae can injure them (skin oils), and that position can make a difference too. If you remove something to image it, you should try to put it back exactly as it was, even to the angle it's resting at.

I have 2...
This one is finished...

and this one should be any day now...

Update :(
The bottom caterpillar never reached adult stage but the pupa might be identifiable.

yes it is.
Euxoa tesselata.

Well, we're on our way then :D
I've seen others type Life Cycle in the type or comments, so I've followed suit with those that I have posted. You might want to add it to yours. If you put 'life cycle' in the Search box, it does bring up a nice number of photos.

Recent submission
Before I found this 'Life Cycle Post' I submitted images of eggs, larva, pupae, and adult fungus gnats that were subsequently identified as Sciaridae. Should I move the images to another place? If yes, I would need instructions on how to.

Would someone know what newly hatched spiderlings feed on? I had a jumping spider with her offspring and put them outside because I could not feed them. Right now I have eggs sacks of cellar spiders in my basement. I would like to rear them but don't know how.

Suggestions will be appreciated.

Spiderling diet
What do they eat? It depends on what kind they are. Some kinds feed on one another before they leave the nest web or whatever kind of birthplace they have. I photographed a wolf spider carrying new hatchlings on her back and what was probably the same spider six days later, identified by locations of the bristles on her legs. The second photo shows fewer babies, but larger ones.

So many adult spiders are missing one leg that I wonder whether they lost it to a hungry sibling in infancy.

In some species, the mother shares her prey with the offspring. There are also vegetarian spiders. Some carnivorous spiders eat pollen or nectar in addition to prey.

That's interesting - thanks.

Creating a life cycle series with more than one specimen
Look at what I've done under the image here.

Lynette. I will try to do the same.

Gnat life cycle
Kalafati, Can I put your fungus gnat life cycle on my web site - We don't have any gnats, and it would be nice to fill in that gap a little. Check out the site and send me a note if you're interested.
