At first, I thought this was a wasp but it looks like a fly.
thx for your answer

Dear A.zanos,
You are correct that this is a fly.  Hover Flies or Flower Flies in the family Syrphidae often mimic stinging insects like bees and wasps, which affords the nonstinging flies some protection.

I returned from a walk in the woods and felt a crawler under my shirt sleeve. I pulled my sleeve back expecting a tick and found this tiny critter instead. He was hanging on for dear life and could not be extracted by hand. We used my “mustache comb” to disentangle it and then snapped some pictures . The last picture shows how small it is compared to a tweezer. It seemed rather soft-bodied…

Hi Dan,
This is a Louse Fly in the family Hippoboscidae.  According to BugGuide:  “This group includes wingless and winged forms. Most winged ones are dark brownish and smaller than house flies. Flat shape and leathery appearance.”
  Winged species have feeble flight and often loose their wings upon landing on a host animal where they can suck blood.  BugGuide also notes:  “Most are found on birds, others on mammals” and we have discovered that some species are found on livestock and others on deer.  Louse Flies can be opportunistic, and if they cannot locate their typical prey, some will feed on human blood.

Hi. I live in the Zona Norte in Costa Rica. Two nights ago, I found a huge green caterpillar crawling in our yard. It was 4-5 inches long and about 2.5 inches in diameter. It didn’t appear to have any hair or spines, or, if it did, they were very short. It also appeared to have narrow, yellow bands. The underside was black, I think. It rather looked like the caterpillar in Alice in Wonderland. In the picture, it’s next to a full size Maglite to give perspective. It made a cocoon the next day. Any help you can provide would be much appreciated.

Hi Lacey,
While we are unable to provide you with an exact species, we can tell you that this is a Giant Silkmoth Caterpillar in the family Saturniidae.
  Adult Giant Silkmoths are often large and spectacular looking.

What kind of spider is this?

Dear Curious creeper,
Several time in recent month, we have tentatively identified large Wolf Spiders as Carolina Wolf Spiders,
Hogna carolinensis, but in your case we are nearly certain that the image you submitted is of a Carolina Wolf Spider, which according to BugGuide can be identified because of:  “Orange paturons (chelicera) and black around the the “knees” ventrally are characteristics of the species.(Jeff Hollenbeck)” and both of those characteristics are evident in your image.  Carolina Wolf Spiders range well beyond the Carolinas.  Though a large individual might bite if carelessly handled, Carolina Wolf Spiders are not considered dangerous.
