Almost definitely (I'm not a regular birder) European Green Woodpecker (latin name: Picus viridis) and it is native to your area according to its species distribution map. "Green woodpeckers are the largest and most colourful woodpeckers native to Britain. They are easily recognised by their laughing ‘yaffle’ call, which they use to demarcate their ...

It's definitely a bird pelvis (synsacrum). Based on the size (~30 cm), it came from a very large bird. Unfortunately, comparative images of bird pelves are rare on the internet. Some possibilities (large birds of Sweden possibly found on the coast): Great northern loon Golden eagle Common crane A loon skeleton (from ...

First, and I cannot stress this enough, you should not go seeking out human pathogens if you don't have the appropriate equipment to handle it at the right safety level. That goes for all pathogens, even ones you might find around your house. In a professional lab, you might get samples from collaborators, clinical samples, vendor, or really an number of ...

It's probably Arbutus unedo, strawberry tree. Native to Mediterranean region and some part of western Ireland. Edit: I've just spot that you found it in California, so it's probably one of north american Arbutus species, eg. Arbutus menziesii.

Its definitely a True bug (Hemiptera), and based on its distinct pronotum and small head I'm guessing its a Wheel bug (Arilus cristatus). It is a common species that is also found in Indiana. They are aggresive predators and are part of the family Reduviidae also known as Assassin bugs. This is not a part of the world I know well though, and there might be ...

I think this is the Chinese Redbud (Cercis chinensis), see this image (from here):

It's a larvae from a ladybird (or ladybug). Judging by the stripe pattern it is a Common Spotted Ladybird (wiki: Harmonia conformis) and from the body shape & size I'd also say 3rd instar. The one you have photographed, and the one on flickr, are larval forms of the ladybug, just like when a catepillar becomes a butterfly, the ladybugs also have a ...

This looks pretty much like a female zebra finch to me (the male have a more prominent feather pattern). See this picture: These birds are not native in Europe, this is correct. But it is always possible that birds escape captivity (or are released) and the live in countries where they originally not belong. I think this is the case with the zebra finch ...

It appears to be a longhorn borer beetle. A more comparable picture is found here. Are there fig trees nearby? Here you will find numerous images of Longhorn beetles.

Crows are omnivorous, and will eat almost anything they find or can kill. In this case the prey looks like a Yellow-Shafted Flicker.

I'm not 100% sure, but I think they look like scale insects (Coccoidea). In particular it looks at bit like a hermaphrodite cottony cushion scale insect (Icerya purchasi)... The white fluffy thing underneath the insects is the ootheca (egg case). The mature insect migrates to the main trunk of its host tree and attaches to the bark. It then secretes the ...

This is a Cattle Egret (Bubulcus ibis), which is a heron in its breeding plumage. When not breeding, the bird is white. See the images for comparision: Breeding cattle egret with colored feathers. Nonbreeding cattle egret, completely white.

Walkingsticks, like that in your photo, belong to the insect order Phasmida (also sometimes called Phasmatodea). The species in your photo belongs to the family Pseudophasmatidae. Texas has two species documented for this family. One is Anisomorpha ferruginea, commonly called the dark walkingstick or northern two-striped walkingstick. The other species is ...

I think this may be a fly killed by the fungi Entomophthora muscae (most likely) or maybe a Cordyceps fungus. These are fungi which mainly attacks insects, and you sometimes see attacks as white, swollen abdomens in flies. These types of fungi are also known to change the behaviour of infected individuals, so that they e.g. climb up tall plants to die, to ...

I have been looking into this for days, but this plant is difficult to identify without its flower. I reached out to a botanist at Dartmouth, who suggests that it is either one of two species-- a nasturtium (Tropaeoleum sp.) or a geranium (pelargonium). The leaves are what are called peltate, meaning shield-like with the stem attached directly underneath. ...

It is definitely a longhorn beetle (Cerambycidae), most probably from the subfamily Lamiinae (Flat-Faced Longhorns, > 10000 species worldwide). I'm however mostly familiar with longhorn beetles from northern Europe, and there might be taxa that I'm unaware of. The overall morphology (e.g. downward facing head, robust build, spined pronotum) is however very ...

Looks like the nymph of a masked hunter. They carmouflage in dust and sand.

I think it looks a lot like a European Pigeon Tick (Argas reflexus). They infest pigeons and they die when infesting humans, which they only do if they are very hungry (yours looks hungry though). May also transmit diseases. Edit: It could also be an Argas vespertilionis (don't know the english name). They infest bats and are a little rounder in shape ...

From the pattern on the elytra (hard upper wings), it looks like you might have a beautiful male Polyphylla fullo. Compare your photos with the P. fullo in this illustration, or photos on the Wikipedia page. edit to fully respond to the comments: I suspect you're right that the antennae plates in your picture are just tightly closed up, giving a different ...

This is an immature "True Bug", order Hemiptera. You can tell this from the general shape of the wings, and from the big "beak", a feature of the Hemiptera. Within Hemiptera, it's possible that with those enlarged front legs, it could be an Assassin Bug, family Reduviidae.

Species are difficult to define. This is because they form over a gradual continuous spectrum via evolution, one species does not suddenly become two, but lineages diverge (perhaps because there is some kind of barrier - like a mountain range - in the way) eventually reaching a point where we class them as separate species. How we define species is debated ...

It's a pied version of the Rock Pigeon (Columbia livia), aka Rock Dove. According to the Cornell Lab of Ornithology, the pied variety of Rock Pigeon is one of any color that has splotches of white on the body. I think that fits your bird very well. It's not a different species, but just one of several color varieties of Rock Pigeon. If you are not familiar ...

I believe it's the Violet Ground Beetle - Carabus violaceus. This is a close relative to the Carabus coriaceus posted by Jon. The purple colour is a give away, but as in many insect groups there are often very similar species. As pointed out in the comments to this anwer, this is the case for C. violaceus and C. problematicus (differences) There are ...

It looks indeed like a Spirogyra, or at least a member of the Zygnematales. And yes, the green things are the chloroplasts (or one long chloroplast?), and they are arranged in spiral. The "empty" space in the middle is likely the nucleus, and the darker circles within the chloroplast(s) could be the starch accumulated at the periphery of pyrenoids.

Nice pictures! From the back pattern, size, and antennae shape, I'd say this is very likely a Cicada Killer wasp (Sphecius speciosus), cf., for instance, this picture taken at a similar angle to yours. There are many good resources online about Cicada Killers, including this page from the MSU Extension Office, and the Wikipedia entry Sphecius speciosus. It ...

This is mostly a guess and loose suggestion, since the picture is not very clear (would need to see the larvae in more detail). However, Bagworm moths (Psychidae), Case moths (Coleophoridae) and Caddisfly larvae (Trichoptera, almost exclusively aquatic) all build similar cases. They construct their cases out if silk and often include debris, pebbles and ...

It's Echinacea. I've linked to one site but if you run an images search with Echinacea as the search term you'll see lots of examples. And here is the WP page. Supplementary Echinacea are members of the Compositae. The flower (the head) in your picture is actually made up of lots of individual smaller flowers (i.e. it is a composite flower). The petals ...

It's not a single grass cell, but this does indeed appear to be a micrograph of a leaf of grass—so it actually contains numerous cells. Here's another image I was able to find with a much more clear description of exactly what you're seeing: Marram grass leaf. Light micrograph of a cross section through a closed (unravelled) leaf of Marram ...

That is a piece broken off of a sea urchin shell. Without it's spines, it's not possible for me to say which species it is.

I believe it is a Garden Orb Weaver spider. The Australian garden orb weaver, Eriophora transmarina, has a strikingly similar body
