Been seeing a ton of different lacewings and their babies 💚💚 look at this adorable little piece of filth 🥰

@midst-decay submitted: Tiny killer collecting his junk.

This is the cutest thing I've ever seen oh my god. Using their lil face snippers to try to pile that corpse onto their back. Absolutely precious. They should maybe calm down a little though or they are going to become a hoarder...

Complete Metamorphosis

I previously wrote about incomplete metamorphosis, where insect babies (nymphs) hatch from eggs more or less looking like adults. Complete metamorphosis is a totally different game--the babies (lavae) look absolutely nothing like the adult form, to the point where you may not even know that they are insects at all. Once you know what to look for, identifying larvae is much easier.

Questions to ask when you see something that might be a larva:

Where do you see it? On a plant? On the ground? In the water?

How is it shaped? Does it have a visible head? Does it have legs?

If it does have legs: how many? What do they look like? Are there any other appendages, like jaws or prolegs?

Photo examples above:

Green lacewing larva. These larva are predatory and have large biting jaws. Some species also use camouflage, covering their bodies with debris which may include the emptied out husks of their prey. If you ever see a white fluffly blob meandering around on a tree, chances are you are seeing a green lacewing larva.

Mosquito larva (Asian tiger mosquito). Mosquitos spend the first part of their life in the water--females lay eggs on the surface of stagnant water, and after hatching the larvae wiggle around with their tails out of the water (they breathe through a tube at the end of their abdomen--you can see a little knob in the photo). It’s interesting to note that mosquitos are flies, yet I don’t think anybody would mistake a mosquito larva for a maggot. Even within insect orders there is substantial diversity.

Lady beetles. While the lady beetle family has a variety of species that look very different from one another, most people picture a black-spotted red beetle when they think of a ladybug/lady beetle. The larvae of these particular lady beetles also look fairly similar, and it can be hard to tell them apart unless you know what to look for. In general, they are black and orange, are textured and look “armored,” and have three sets of fairly long legs. You will often find them on plants that have aphid infestations, as the larvae are predatory on them.

Leaf beetles (blue dock beetle). Leaf beetles are another very large group with few similarities between species. You will typically find leaf beetle larvae (you’d never guess) on leaves of their host plants. These larvae can do a substantial amount of damage to crops if they go unchecked. Like lady beetle larvae, they have three sets of legs and a segmented, textured body. When I first saw these larvae, I was able to guess what species they were because this plant was infested with the adults (and they were the same color!)

Scarabs. Another beetle, but this one is much different. Scarabs are an enormous group of species, but their grubs generally look the same and develop concealed underground or in rotting wood. The grubs are soft and fleshy, with three sets of very long legs and a prominent head capsule. It is fairly rare to see one without busting up old logs or digging holes, but they do occasionally venture out in to the wide world. The adult shown here is a masked chafer, but I’m really not sure about the ID of the grub (they are hard to tell apart!)

Io moth. On to caterpillars! Most people are familiar with caterpillars (the larvae of butterflies and moths), and may even be able to identify (or at least recognize) a few. But caterpillars can be tricky as well, because they look so different from one another, and there are a few other types of insects with caterpillar-like larvae. Sawflies, for instance, can look almost identical to caterpillars, except they have a different number of prolegs. Prolegs are those little fleshy suction-cup things caterpillars have to keep them from falling of leaves they are feeding from and living on, but they are not true legs, and butterflies/moths rarely have more than 5 pairs of prolegs (inchworms and loopers have two or three sets!). Sawflies will have more than 7 prolegs. Some caterpillars protect themselves with venomous spines, like this io moth caterpillar. If you are able to get a side or bottom view of a caterpillar, you can see the number of prolegs to confirm that what you see is a caterpillar after all.

Tawny emperor. These caterpillars are interesting to me, because their head capsules are covered in little horns (I think it makes them look like Dutch rabbits!), but otherwise they look fairly standard for caterpillars. As with all larvae, you’d never guess what the adult looks like from seeing the babies.

@measurerain submitted: hiya!! sorry that the photos arent very good but we were wondering if you could ID these :D we’re in texas

love your blog <3 thank youuuuuuu!!

Hello! Thank you! These photos are perfectly good. The first fellow is a green lacewing larva - they cover themselves in environmental debris as camouflage. But in the first photo of the underside, you can see their enormous jaws used for snatching up delicious buggy prey:

Neat :) The other fellow is a velvet mite! They, too, are predators. Neat finds! Thanks for sharing!

@yeoldedeadlights​ submitted: Any idea what this guy is? I found him crawling over my sofa! He’s tiny with pincers at the front, it looked like he’d disguised himself with dust and fluff! Scotland

Yeee it’s a green lacewing larva. They’re sometimes called trash bugs because they like to camouflage themselves with debris from their environment as you can see here :)

My mom videoed a trash bug today! It’s also called a junk bug, and my dad bumped it in this video but don’t worry it wasn’t hurt and we put it in our garden to keep it safe!

I love these lil dudes. If I were a bug I think I’d pile trash onto my back as camouflage too. These dudes are actually lacewing larvae! Excellent. Thank you for sharing :)

[onenicebugperday]

Has anyone submitted a junk bug before?? At least, I think that’s what this is! I had to send a video I took a couple years back because I love the way this funky little guy moves!! I hope the video quality is okay ^^; (also, there’s another little dude crawling at the bottom of the screen!!)

No, I’ve never had one submitted! But yes that’s what it looks like. Junk or trash bugs are the larvae of green lacewings in the family Chrysopidae. They’re also called aphid lions since they are predators that often prey on aphids. The junk on them is camouflage - either debris from their environment or the corpses of their devoured prey. Fun! Thanks for sharing such an interesting dude.

I found a junk bug in my garage! Also known as a debris-carrying green lacewing larvae apparently. I saw it moving in the garage which intrigued me because i didn’t know of such a bug and its really cool so i helped it outside and watched it put a piece of debris back onto its back. so freaking cool.
