Dinosaur eating insects!

Giant insects can eat tiny dinosaurs.

In this case, the giant insects are praying mantis, and the dinosaurs are hummingbirds and other small birds. In some cases, maybe most cases, this involves small birds like hummingbirds being taken at nectar sites (natural or otherwise) by introduced species of praying mantis in the US.

Here’s the info from the recently published paper:

Bird Predation By Praying Mantises: A Global Perspective, by Martin Nyffeler, Michael R. Maxwell, and J. V. Remsen, Jr.

ABSTRACT
We review 147 incidents of the capture of small birds by mantids (order Mantodea, family Mantidae). This has been documented in 13 different countries, on all continents except Antarctica. We found records of predation on birds by 12 mantid species (in the genera Coptopteryx, Hierodula, Mantis, Miomantis, Polyspilota, Sphodromantis, Stagmatoptera, Stagmomantis, and Tenodera). Small birds in the orders Apodiformes and Passeriformes, representing 24 identified species from 14 families (Acanthizidae, Acrocephalidae, Certhiidae, Estrildidae, Maluridae, Meliphagidae, Muscicapidae, Nectariniidae, Parulidae, Phylloscopidae, Scotocercidae, Trochilidae, Tyrannidae, and Vireonidae), were found as prey. Most reports (>70% of observed incidents) are from the USA, where mantids have often been seen capturing hummingbirds attracted to food sources in gardens, i.e., hummingbird feeders or hummingbird-pollinated plants. The Ruby-throated Hummingbird (Archilochus colubris) was the species most frequently reported to be captured by mantids. Captures were reported also from Canada, Central America, and South America. In Africa, Asia, Australia, and Europe, we found 29 records of small passerine birds captured by mantids. Of the birds captured, 78% were killed and eaten by the mantids, 2% succeeded in escaping on their own, and 18% were freed by humans. In North America, native and non-native mantids were engaged in bird predation. Our compilation suggests that praying mantises frequently prey on hummingbirds in gardens in North America; therefore, we suggest caution in use of large-sized mantids, particularly non-native mantids, in gardens for insect pest control.

  1. We were watching some hummingbirds in BC the other day, and I was thinking, “F*cking miniaturized dinosaurs!” More than some birds (what the hell do I know?) they seem to have this lizard (or dinosaur?)-like aggression, opportunism and wariness.

    Also they’ve achieved one of evolution’s Master Goals, which is the ability to zoom wildly about in all directions without using a quadcopter.
