One of the balancing organs seen in flies, these club shaped organs are the modified rear wings.[see picture]
hamulate coupling
A wing coupling mechanism used in Hymenoptera. A row of small hooks (hamuli), on the anterior margin of the hind wing, engage with a sclerotised anterior margin of the fore wing.
Small hooks on the front edge of the hind wing to link it to the fore wing in Hymenoptera.
Organ for sucking liquids.
Forewing of a heteropteran bug, has a membranous tip.
Insect which has an incomplete metamorphic life cycle, no pupal stages.
Unequal numbers of tarsal segments on all legs.
heteroneurous venation
Lepidoptera, in which the number of veins in the hind wing is less than the forewing, cf homoneurous. Considered to be the more advanced condition.
histeroid aedeagus
Aedeagus in which the phallobase and parameres form a tube surrounding the penis. This type is found only in Sphertididae, Synteliidae and Histeridae.
Insect which has a complete metamorphic life cycle, with pupal stages.
Of Diptera, referring to the eyes touching at the top of the head. Holo means whole.[see picture]
homoneurous venation
Wing venation in which the fore and hind wings are similar
Two species which have been given the same scientific name, when discovered one species has to be renamed.
humeral angle
An area at the base of the wing, when the costa curves sharply backwards anteriorly.
humeral vein
Small cross vein in the humeral region of the wing running from the costa to the sub-costa.
Sweet liquid extruded from the anus of aphids.
Transparent and homogenous. When referring to a wing, suggests no colour patterns.
Life cycle in which there can be two or more different types of larvae.
An organism which is parasitic on a parasite.
Under, beneath, lower. Less than normal. A lower state of oxidisation.
Possessing a vertical head with mouthparts at the bottom.
Part of an insects mouth parts arising behind the mouth and in front of the labium.
hydrofuge surface
A portion of the body surface covered with dense hairs, which often have a complex structure. Under low magnifications, these areas have a characteristic dull sheen. Hydrofuge surfaces repel water and in some cases they form a plastron.
(pl. hypomera) (of pronotum). That portion of the pronotum which is visible from the ventral side; when there is a lateral pronotal carina, this is the portion below that carina (the pronotal disc being above it). The postcoxal projection in Polyphaga is part of the hypomeron.
hypopleural bristles
Row of bristles which curve round on the side of the thorax of some flies.
(meropleuron) Think itís a plate on the lower side of the thorax in Diptera. May be bare, with weak hairs or strongly bristled.
