Taking a closer look at insect eggs

Robert and ogdenjj - welcome, and thanks for following my blog!

*I don't know how this post will appear, because there were several html code errors that I couldn't fix. Anyway, here goes!

Today's post is gonna be about the eggs of some of the most destructive garden insects in the garden, and I hope you enjoy it!

Stinkbugs are found daily in my garden, but noticeably more frequently on tomatoes, cucumbers, corn, and okra than most other things. Regardless of how many egg clusters that are found (then squished), it seems that a few are always missed somehow. The eggs are pearly white, and quite beautiful if you ask me....I know, pretty weird - but how does an adult stinkbug lay them so perfectly aligned? I'm amazed at the whole process....Typically, we have the green stinkbug variety where we live, and here's a picture I took of one the other day...


Anyway, these were found on a pod of okra the other day while harvesting, and a picture was hastily taken. I immediately knew what it was - stinkbug eggs....


Photo below - thanks to a microscope with photographic capabilities, here's what they look like much closer. The little "ring" on top of each one is the doorway to their new world, but none of these are ready to hatch yet.....Finding any of the eggs before they hatch is perhaps the best way to keep them from ruining your gardening efforts. Each evening, I just play with Jude and inspect the bottom side of leaves for any eggs, then crush them with my fingers. Hehe....I really take it to 'em! Afterall - i'm the "EG-nator"...hehe.


Photo below - now, it's time for some caterpillars - most notably the tomato fruitworm, and fall armyworm. These 2 worms cause the most damage to my tomatoes each year, because they hatch out in such high numbers - and can ruin a crop pretty fast, too! The tomato fruitworm (or corn earworm as it's frequently called) are enemy #1 around here, because they actually bore into the fruit - completely ruining each one, of course. Here are the eggs as they appear on leaves.....

                                         













                                          


I find some everyday, and all of the ones in the previous photos were found just in the last 4 days...Yeah - trust me, you have them too...

Now...let me show you what they look like up close. Actually, they're quite beautiful, and almost look like beads for some type of jewelry or something....










In the photo above, you can actually see the caterpillars as they begin to hatch out. The eggs themselves look so fragile - as you can see some of the paper thin spheres have already been opened. Pretty freaky, huh? Ha! I'll try to get some magnified photos of them when all have hatched, because I still need to identify which eggs belong to a certain species of caterpillar.
In other insect news, i've found the first squashbugs for the year while they were doing the "big nasty"on my yellow crookneck plant, and ended their happiest moment right then and there. It's quite strange that none showed up until the middle of July, as most years are unbelievable before the middle of June. I'll have to inspect the plants daily now just to stay ahead of them, but that's no problem at all.....I love killing squashbugs!

Take care, and happy bug hunting!

Thanks, EG! WOnderful pictures. I hate it when the bugs engage in extra curricular activities in the garden. It makes me feel so violated.

Yikes...I get the creepy crawlies just looking at those pics! I've never come face to face with a tomato horn worm before. I'm sure the first encounter will be unforgettable.

Great egg photos!!! The squash bugs are all in my garden this year! I've been busy squishing them and I pick up their eggs on duct tape. It works to catch a group of the little baby squash bugs too. They're to fast to catch by hand. Happy egg squishing.

Melissa said...

Cool post! I have those stink bugs on almost everything at the moment - and am fighting the fire ants. Ouch!

Excellent Post :)

I havent found too many bad bug eggs in my garden as of yet, but I believe I've found lots of Wasp eggs. The kind that they usually attached to the hornworm. I've found them all over the my outdoor greenhouse, a good thing if they are wasp.

I know the wasp, ants and ladybugs are keeping many bad insects in line. I've actually found a few wasp sleeping up in my cucumber canopy...lol. I thought they were dead, but I shook the plant and he flew away.


Good Luck with in this heat!! It's getting hotter everyday!

I had no idea! Thanks for the new gardening info, I will definitely be able to put this to good use.

I have been seeing squash bugs around here for a month or so I'm hoping wrapping the transplants stems in pantyhose before I planted them in the garden will help.

Cool, i'm glad everyone liked the post!

It's always good to see good close up pictures of these eggs! Helps to know what to look for! I saw some baby squash bugs in the garden yesterday...guess I missed those eggs! Drats!

debiclegg said...

EG, thanks for the useful info in this post. It will help me to find the BAD EGGS!! I haven't had as many squash bugs this year either. I have only seen 2 and I quickly did my best EG-NATOR imitation and they were destroyed!!! As I have been running up and down I-65 this week to and from Nashville, I have wished that I had time to run by and see your garden in person!!! Do you think I could convince 3 teenagers to stop on the way home tomorrow? Probably not... too bad!!

Cheryl said...

That's the coolest camera feature. Man, what will they come up with next?

Cheryl said...

Don't know what happened to the comment yesterday, but would you tell me a little about the camera you took the pictures with? That close-up feature is amazing.

Engineeredgarden said...

debbie - good for you! Show those squashbugs who's the boss of your garden...

Cheryl - it's a microscope that has photo capabilities. I think the cost is around $1,200

Whoa! Now that's cool! Gave me the heebie jeebies, but cool, just the same...

Engineeredgarden said...

sb - i'm glad you liked it...

The egg closes ups are pretty crazy!

Stefaneener said...

Have fun smashing! I enjoy the hunt some, but it does get old. You must be awash in bugs - the South is a challenging gardening area.

foodgardenkitchen said...

Your squash bugs didn't show up until now because they were having all the fun in our garden since mid-June and figured "why leave?" I can't tell you how many "couples" I squashed in the past month - they're certainly easier to get at that moment :)

Great post - very educational. You've got a lot of caterpillar eggs to contend with...
