The temptation to hit "bug reports" was almost overwhelming! Anyway, did my PhD on Scelionids with Masner, and wanted to drop by and say "yeah" for whoever is doing this - so "Yeah!"

[edit] Symphyta groups

Though considered paraphyletic with the Apocrita in some taxonomies, this should not preclude their mention among the Hymenoptera. Superfamilies listed, not Wikified, until some work can be done for at least some of these groups.azwaldo

[edit] What to mention

Why would you list some families for the Vespoidea and not for the others? Unless you have a good reason, would it not be better to be consistent and leave them out?Dave 04:57, 10 February 2006 (UTC)

[edit] Order of superfamilies

The order looks as though it is in some sort of evolutionary progression. If that is not so, if there really is no logical basis for the order, would it not be better to arrange them alphabetically?Dave 05:06, 10 February 2006 (UTC)

[edit] one small addition?

while the ancient Greek translation is a very impressive find. The name Hymenoptera actually is derived from hymeno, god of marriage and ptera wing. which refers to the joining of the wings by a hamuli. the hamulus are a minute series of hooks on the wings of Hymenoptera that allow the wings to join and beat in unison while in flight.

I just wanted to see if this is a worthy addition to this article. As pretty much every insect has membranous wings and apart from the hamuli like structures in some Lepidoptera the hamulus are one of the defining factors of Hymenoptera.

just wanted to get some opinions before making any changes.

I'm silly Hamuli are mentioned in the article, but is it ok if the information about the first half of the name Hymenoptera is added? (Entoman09 06:00, 29 November 2006 (UTC))

I don't know if the name actually does derive from Hymeno. Now, I'm not sure about this, but, according to the OED, it appears that Linnaeus was going off of some Latin word (perhaps hymenoptera) which comes from a Greek word ὑμενόπτερα which comes from ὑμήν. Sadly, my Latin dictionary doesn't have hymenoptera, nor does my LSJ have ὑμενόπτερα, so I can't look up the origins of these words. In any case, the OED mentions ὑμήν as the apical prefix of the word, and so I think that we should stick with that, unless you have some other compelling evidence. If you have access to Linnaeus' writings or something, I think that would rather definitely settle it. Cerealkiller13 07:03, 29 November 2006 (UTC)
While I don't have access to Linnaeus' writings I'm just referring to my 2005 edition of Borror and Delong's introduction to the study of insects. However, that text may be just Defining Hymeno with it's Greek mythological meaning. Hymen was the Greek god of marriage but it still refers to any kind of membrane. So both meanings are correct. I guess its open to interpretation and relative to whom is talking about it. eh?

Entoman09 07:44, 29 November 2006 (UTC)

Well, I don't think this is the case. Either Linnaeus sort of made up the word (as biologists often do), and then the correct definition is born from his intent, or else he was taking from some premade word, and then there is probably a definitive etymology for that word. Although I will certainly admit I don't know which one is the case, and so I will heartily admit my etymology could be wrong. Cerealkiller13 17:17, 29 November 2006 (UTC)

[edit] Sex determination

This article implicitly states that 50% of the offspring in a Hymenopteran colony are males by its suggestion that the male gender is determined by a gene. Deeming from what I've read about sex ratio in ant, wasp and bee colonies, this is obviously not the case; all of the workers are sisters at least in the literature. If gender is genetical in Hymenopterans, surely the male-gene locus must be homozygous in 50% of the cases - if both the mother (who usually is the mother of the father and thus must carry all of his genes) and the father (who obviously is a male) carries the allele?--Gunnar Mikalsen Kvifte (talk) 22:59, 12 February 2008 (UTC)

I think maybe you misunderstand haplodiploidy. Gender is determined by whether an egg is fertilized or not, which is under complete control of the egg-laying female, since fertilization occurs at the time the egg is laid; she either releases stored sperm from the spermatheca, or she does not. If a female fertilizes all of her eggs, they will all be female. If she fertilizes none of them, they will all be male. This article directs you to the one explaining haplodiploidy, which you may wish to read more closely. The comment about sex being affected by a locus is a special case which is exceedingly rare, since the sex locus referred to has many different alleles, and will almost never be homozygous unless there is substantial inbreeding.
