Entomology (Study of Bugs)/Fleas?
Hoping you could help me. I was recently in Manuel Antonio, Costa Rica and on our third night we saw many bugs in our bed that looked like fleas. They were jumping. Even after we had the hotel change the sheets they reappeared leading us to believe they came from our mattress. (Photo BUGS1)
The hotel then transferred us to another room; however, we saw what looked like a host of flea eggs all over the comforter. The bed was also very damp due to the high humidity and rainfall. (Photo BUGS2)
The hotel supposedly had an expert identify the bug after we left and said it was a Mushroom Beetle (Family Cryptophagidae). I don't know anything about this bug and would like to know what it is for health reasons.
My inexperienced assessment is that these are fleas given their ability to jump as well as what their eggs look like but would greatly appreciate your expert opinion.
I have examined your photo and I am sure that these are springtails( members of the Order Collembola) They occur in very large numbers just about every place on Earth including on snow. They thrive in moist conditions. They are harmless feeding on fungus spores.There are no health hazards here. They have a device that is cocked under their body which is released when they are disturbed springing then into the air. Think of a cocked mousetrap dropped upside down.
The shape in the photo and the jumping tells that these are definitely Collembola. Look them up. They come in different shapes
The "expert" the hotel hired is no expert. Any entomologist can tell a springtail from a beetle
