Mantidae (part 2)

Thanks to Student Doctor Inna, I now have the female counterpart of the European Mantis. I thought I would post the photos in comparison, as well as provide more information about this species. The female is more drab colored, a golden brown/olive green almost - most likely for better camouflage. Also, she is about twice the size of the male mantis. I waited a day before preparing her for pinning, and the jar became coated with a slick pungent liquid - possibly pheromones. This is the first non-Lepidopteran I am pinning using the spreading board, so hopefully she will come out looking fantastic!




Mantodea; Mantidae; Mantis religiosa (female)
Common Name: European Mantis

M. religiosa originated in southern Europe, hence the common name. It was accidentally introduced to North America on nursery stock. They are now found across the United States, and are most easily identified by a dark spot on the inner side of their fore coxae. The female's spot is entirely black, but the male's has a white spot with a black outline. M. religiosa is the state insect of Connecticut. It is also good to note that when in Europe, it is simply called a praying mantis, in the same way that Brazil nuts in Brazil are simply called nuts.

Mantidae

Finally I have a member of the order Mantodea! There are only two North American families: Mantidae, which contains the majority of the species, and Mantoididae with one species, Mantoidea maya - a small mantid (15-17mm long) with a square-like pronotum; it is only found in southern Florida in the United States. Needless to say, this specimen, found in California and exceeding 40mm, is a member of Mantidae. Also, there are only 16 species within Mantidae, in North America, so identification to the species level was rather simple. Based on its size, color, location, the time of year, and the distinct black and white circular marking on the inside of its frontal femur, it is Mantis religiosa. I also suspect it is a male because it seemed to be carrying a spermatophore, a protein/carbohydrate rich gift that some crickets, katydids, mantids, and other insects present to a female as a nuptial gift. Unfortunately for male mantids, females do not stop at the spermatophore...



Mantodea; Mantidae; Mantinae; Melieae; Mantis religiosa
Common Name: European Mantis (male)

Mantids are large, elongate, rather slow-moving insects that have distinct, modified front legs. Their fore femurs are raptorial, modified so as to facilitate hunting. The head is very mobile, and they prey on any insects they can catch. The larger species have even been known to stake out hummingbird feeders to catch the small birds when they come to feed. Mantids overwinter in the egg stage and the eggs are deposited in an egg case on twigs or grass stems; it may contain over 200 eggs. If confined, the nymphs will consume one another unless there is ample food. The female also consumes the male after or during mating. Mantids have been used as biological pest control, but it is not recommended because mantids do not discriminate between useful and harmful insects. They have also been known to stake out beehives and consume bees going to and from the hive.
